Schlegel terminal blocksa synonym for safety
Only a few years after the foundation ofthe company in 1945, the first „Schlegelterminal“ was introduced in 1950 whichalready fulfilled all the prescribed condi-tions, such as safe operation and function-ality.At present many millions of terminals bySchlegel Elektrokontakt are in use world-wide and all share the highest quality fea-tures.The Schlegel quick-assembly terminalsare standard terminals for industry, espe-cially for electrical machine control sys-tems, for switch, distribution and measure-ment units and for elevator and appara-tus engineering. The terminals are suitablefor high and low voltage as well as forDC and AC. The particular advantagesof the terminal blocks are their short as-sembly times and their small dimensions.The requirements which our products haveto fulfill are increasing, due to the use ofmore and more complicated machinesand devices and the need for easier, moreextensive processing.The variety of fields of application callsfor an increasingly large range of prod-
ucts. The ability to offer top quality at alllevels of the product ranges depends onan efficient team. The goals we have setourselves in terms of quality, functionalityand technical operating safety were onlyable to be achieved thanks to decades ofexperience in development, fabricationand testing. We meet high quality require-ments providing a complete documenta-tion according to ISO 9001.

An important condition for the produc-tion of high-quality terminals is precisemould making.Therefore, we manufacture our fabrica-tion tools ourselves for years thus retain-ing one of the most important quality cri-teria.

Schlegel terminal blocksQuality features
Insulating materialsfor terminal casings
Creepage path and air path
The casings of our terminal blocks aremade of high-quality polyamide. Nationaland international regulations prescribewith utmost precision which characteristicsthe plastic must have.
The adherence to these regulations is aconstituent part of the quality assurancesystem according to DIN ISO 9001 whichour company has introduced. In addition,the relevant authorities must approve thematerials. Regular manufacturing controls
made by the certification authoritiesmonitor their exclusive application.
Due to the variety of certifications whichour terminal blocks have obtainedworldwide, only the best material issuitable for the sum of all requirements.Consequently, the approval marks on theterminals ensure the application of rawmaterials of the highest quality only.
The creepage path is the path betweentwo live parts with different potentialsalong the insulating material surface.The air path is the thread dimensionbetween two live parts with differentpotentials.Since normally the creepage path mustbe longer than the air path, the creepagepath is lenghtened by means of ribs orchases.National and international regulationsprescribe how long creepage and airpaths must be. Their lengths depend onthe voltage between the live parts, the
degree of soiling and the excess-voltageclass.With regard to the creepage path, thenature of the insulating material is alsotaken into consideration.The higher the quality of the insulant, thesmaller the creepage distance can be.Since shorter creepage paths allow smallersizes, high-quality plastics provideadvantages with regard to the externaldimensions of a product.
Connecting cross section The rated connecting capacity isindicated on the back wall of the terminalblocks. This is the cross section which theterminal block in single, multiple and finecore design can accommodate. All thedata and tests such as electric loading,heating and mechanical safety refer tothis. These tests are not only carried out inour firm but are part of the type-testscarried out by the testing bodies in orderto obtain national certification. This isdocumented by the permission to displaythe marks on the terminal blocks.The terminal blocks must allow the con-ductors to be connected without parti-cular preparing. Straightening single andmultiple conductors as well as twistingfine-core conductors do not count asspecial.Soldering of fine-core conductors is notallowed, because the soldering-tin tendsto creep.When using wire end ferrules, theconnectable cross section may be reducedby one level. This and other factors makethem unnecessary for SCHLEGEL terminalblocks.
Up to a cross section of 35 mm² theterminal blocks must also be able toclamp the two next smaller cross sections.In the case of SCHLEGEL terminal blocks,the nominal cross sections are graduatedin a manner that all the existing crosssections from 0.5 to 240 mm² are fullycovered.It must be stressed that SCHLEGELterminals up to a nominal cross section of4 mm² also clamp conductors down to adiameter of 0.2 mm².In the U.S. and the Anglo-Saxon countriesthe AWG number is used as a crosssection indication. The AWG cross sectionindication is to be found on the terminalblock if it is accordingly certified.
Protection against accidental In accordance with VBG 4 (UVV)protection against accidental contact isrequired for every electrical device.According to the arrangement of the units,this protection must meet with certainrequirements , whereby a distinction ismade between protection of the fingersand protection of the back of the hands.

This is tested by making an artificial metalfinger with movable finger joints. The fin-ger is connected to an indicator lampand used to test whether parts under volt-age can be touched.Safety from finger-touch is required withina planar circle measuring 60 mm in di-ameter which is imagined around an “oc-

should be noted that the test finger is notpermitted to grip the entire periphery ofa cover. It is therefore suf ficient to use acover which only prevents contact fromthe front.

Metal parts
Types of connectionScrewed connections
The metal parts of the quick-assemblyterminals are made of a high-strengthcopper alloy ideally suited for electricalconnections. They are nickel electro-plated, and in some cases also tin-plated,in order to guarantee a high resistanceto corrosion.
One of the most important elements ofscrew-type terminal blocks are the screws,the quality of which largely dictates thequality of the terminal connections. Thescrews must not break off, must be ableto withstand strong torques above thespecified ratings, and must not fuse withthe metal of the main thread even underthe highest stress. For this reason, rolledsteel screws with a good galvanic surfacecoating made from passivated zinc areused for SCHLEGEL terminal blocks.
In rolled screws, the structure of the ma-terial is compressed and strengthened,whereas in turned screws the fibres arecut off in the vicinity of the screw thread.Because of this, and because of the stressconcentration on the neck of the screw,turned screws are considerably weaker,especially if they are made of brass.
Structure of a turned screw
Structure of a rolled screw
Thanks to the combination of steel screwsand main threads made of copper alloyor steel, an unintentional fusion of brasswith brass is successfully avoided withSCHLEGEL terminal blocks.
The contact system of SCHLEGEL ter-minal blocks with high-elastic contactbrackets guarantees reliability in the fol-lowing six ways:
1. Reliable wire insertion2. Reliable prevention of screw loosening3. Reliable contacting due to high elasticity4. Reliable wire protection5. Reliability thanks to closed system of forces6. Reliability thanks to high connection torque

AssemblyAssemblyAssemblyAssemblyAssembly The SCHLEGEL quick-assembly terminalshave the advantage of extremely shortassembly times thanks to their interlockinginsulating bodies. They can be mountedon standard support rails according toEN 50 022 in the following ways:
1.By pushing the pre-assembled blocksonto the rail
2. By snapping the pre-assembled blocksonto the rail.Important: once snapped onto the rail, thefeet of the terminals are relieved fromstress, so that the plastic cannot fatigue
3.By snapping or pushing individualterminals onto the rail
As shown in the illustration, individualterminals can be easily exchanged byshifting the adjacent terminals slightly(approx. 3 mm).
Changing individual terminals First free the respective terminal bypushing the adjacent terminals awayslightly (approx. 3 mm), then lever it outgently by applying a screwdriver to theterminal foot.

If there is not enough space on themounting rail for the required terminals,it is possible to place the standard Fix-block terminals on the upper level andmount the SCHLEGEL pickaback terminalsbelow. This two-storey arrangementallows twice the number of terminals tobe accommodated on the same lengthof rail. The pickaback terminals arebridgeable through-terminals for 4 mm².The upper level can be used to mount allFixblock terminals up to 16 mm²,including special terminals.
Pickaback terminals
Separator terminals serve to disconnector break current or voltage circuitswithout removing the conductor from theterminals. This is achieved by removingthe disconnecting plug TS.This is a captive plug which can beloaded up to 16 amps and snaps intoboth positions.The separator terminals can be useduniversally by selecting the appropriateplug.
By using DS type diode plugs, it ispossible to control the direction of thecurrent. The diode plugs are easilyexchangeable and the forward directionis instantly recognizable from the colour-coding of the plugs. The diode plugs aredesigned to prevent incorrect insertion.
Separator terminals are available in redand blue to allow instant recognition ofthe assignment of red and blue diodeplugs to the terminals.
With the quenching diode plug, twoadjacent terminals are connected by adiode which is thus positioned in theblocked direction parallel to the inductiveload and prevents excess voltage whenswitching off.

With the WS20 type adjustable resistanceplug, the measuring cables of resistance-dependent precision instruments can betuned to a fixed resistance value.These plugs are equipped with finelyadjustable Cermet variable resistors andcan be steplessly regulated to all valuesbetween 0 and 20 ohms.
With the aid of the BGS type bridgerectifier plug, it is possible to feed anAC voltage on one side of two terminalsand tap a DC voltage on the other.
Neutral wire separator terminals are pre-scribed by the VDE specifications for theinstallation and operation of powerplants in public places (VDE 0108), ac-cording to which an insulating test mustbe possible for every circuit without dis-connecting the neutral wire from the indi-vidual terminals.These requirements are easily and quicklyfulfilled by SCHLEGEL neutral wire sepa-rator terminals.

Fuse terminals When fitted with fuses, the fuse terminalsfacilitate the protection of conductors withcurrents of up to approx. 250 V/10 A or24 V/30 A.SCHLEGEL fuse terminals are equippedwith G-safety cartridges measuring 5 x20 mm. In the IKSI4 type, a time-savingbayonet connector is used as afuseholder, whereas a plug-in insulatedhandle is used for the particularly narrowIKSI5 type fuse terminal.A further variation is the fuse terminalIKFSI5 for automotive fuse-links up to 48V/30 A.

Earth terminals The earth terminals with the 3-fold safetyfunction are instantly recognizable fromtheir green/yellow insulating bodies andcan be mounted between any other termi-nals on the support rail, which thus servesas a PE busbar.The earth terminals can be snapped ontothe support rail from above. The catch isclosed by tightening the middle screw,thus ensuring the first connection with therail = first safety function.By adding a conductor, the terminal isautomatically provided wiht an addi-tional connection to the rail = secondsafety function.By adding the second conductor, the ter-minal is provided with a further connec-tion to the rail = third safety function.
Earth terminals
PE/N-combined three-wire terminals fordistribution systems serve to provide asmany outlets as possible within a con-fined space for one to three-phase con-sumers. the terminals are equipped withall the necessary features for single-phaseconsumers, i.e.
1 screw connection for the PE conductor1 screw connection with disconnecting
device for the neutral wire and1 through-terminal with two screw
connections for the phase conductor
If more than one phase conductor is re-quired in the case of polyphase consum-ers, it is possible to obtain the necessarynumber of phase conductor leadthroughsby adding standard through-terminals,e.g. IK5.

Universal separator terminalIKT10
The universal separator terminal IKT10allows a wide range of wiring configura-tions, being equipped with various acces-sories for additional disconnecting and
switching functions besides the standardseparating switch. For example, 4 mmSTB4L type test sockets can be screwedinto both sides of the separating switch inorder to connect measuring instrumentswith the test plug PST4. Also, cross-con-nections can be made at these test-socketusing a VST10 type connecting plug. Afurther cross-connection between two ad-jacent universal separator terminals ispossible using the switchable VBL10 typeconnecting link.For special applications, a VBT 10-4 typeswitchable four-fold cross-connecting linkis available which, when fixed non-distributively, allows the connection be-tween four adjacent universal separatorterminals to be disconnected simultane-ously.

Three-storey wiring terminalsfor 4 mm2
Railless terminal blocks
In large installations, these terminals al-low the phase, neutral and earthing wireof any one circuit to be accommodatedcompactly in a terminal only 6 mm wide.
Three-storey wiring terminals are avail-able in 6 different versions, each with the
There are many reasons for using terminalblocks without rails. Above all, there isno need for assembly aids such as rails,partitions, end sections and end clampbrackets, thus reducing costs and stock-keeping requirements. Our terminals arerecommended when limited space isavailable, or if further terminals are to beadded subsequently to a block. RaillessSCHLEGEL terminal blocks are availablein two versions, one for 0.5 - 4 mm2 andfor 0.5 - 16 mm2. Since the individual ter-minals lock securely into one another, allthat is needed to hold them in place is asingle screw after every 10th or 15th ter-minal.

Initiator terminalsInitiator terminalsInitiator terminalsInitiator terminalsInitiator terminals Initiator terminals serve to group all theconnections required for wiring an initia-tor, e.g. a proximity switch, inside a termi-nal housing. The power supply connec-tions (+ and –) can be linked by means of
same shape and size. The differences liein the various combinations of
- earth wire terminal on mounting rail- phase through-terminal and three diffe
rent types of netural wire sockets withisolator on busbar
- with or without isolator as through-terminal
Also available for polyphase systemsare single and double-pole through-termi-nals for phase conductors only, whichmay be combined with earth wire termi-nals on the mounting rail.
The individual function ranges of the ter-minals are indicated by colour-coding,whereby phase through-terminals aregrey, neutral wire terminals blue andearth wire terminals yellow/green.
This colour-coding, plus the fact thateach connection and separation pointcan be labelled with an identificationtag, makes the entire system verystraightforward, even when installed. Allterminals have provision for cross-con-nection.

Screwless Terminal Blocks
One of the remarkable features of the screwless through and neu-
tral-wire separator terminals is the wireinsertion from the front. This allowsspace-saving mounting of the termi-nal blocks, namely side by side, closeto the cable channel.The connection system of cage-clampterminal blocks does not basically dif-fer from the connection system of screw-type terminals: In both cases the con-ductor is gripped in the clampingbody and thus makes a contact be-tween conductor and clamping body.
On a screw-type terminal a plate ispressing the conductor against the bot-tom of the clamping body when tight-ening the clamping screw, whereason the cage-clamp terminal a preloa-ded spring pulls the conductor againstthe busbar (=clamping body) by itsown force.
For connecting the conductor the springmust be opened by means of a screw-driver or similar tool. The conductor isinserted through a window in thespring leg and once the tool is re-
moved, the spring force pulls the con-ductor against the clamping body. Thescrewless quick-assembly terminalblocks fit on support rails acc. toEN 50 022. The insulation bodies aremade of unbreakable polyamide 6.6.Once snapped onto the rail, the earthterminal with green-yellow insulationbody gets immediate contact with thesupport rail and thus taking on thefunction of the PE conductor. The earthterminal offers an additional labellingfacility in the middle of the insulationbody.
