These designs are now welded core and encapsulated to provide the highest quality electrical performance. The trans- former coil is completely surrounded by epoxy, making the unit impervious to external elements. The lamination core is welded to provide superior quiet performance.

These include primary and secondary leads out, integral fuse, and spade-type terminals and our standard which is a touch proof terminal block. Consult your local GE Sales Office for complete technical applications data. —Standards: Type IP units conform to NEMA ST20. They are UL listed under UL-506, File E—2739, and C-UL listed. —Insulation Classes: Generally, 150 VA and below are 105°C insulation class, 55°C rise. 200 VA and above are 185°C (NEMA), 180°C (UL) insulation class, 115°C rise. Maximum surface temperature rise is 65°C above ambient. —Frequency: 60 Hertz is standard; 50 Hertz is available as an option. —Voltage Regulation: All designs 2.0 kVA and below are compensated for voltage drop. Generally, this compensation ranges from 10% in the smallest rating to 3% for the largest. All machine tool designs meet or exceed NMTBA regulation requirements. —Series-Multiple Secondary Connections: Transformers with 120/240 V secondaries (series-multiple) may be connected for 120 V, 240 V or 240/120 V three-wire. Jumpers are provided. —Overcurrent Protection: Type IP transformers are low imped- ance transformers that require overcurrent protection for most applications. They provide for optional integral primary and/or secondary fusing. —Mounting Dimensions: Type IP transformers are lightweight, small, and designed for minimum mounting dimensions. Many units will fit competitors mounting footprints.

DescriptionType IP transformers are core and coil units designed for machinetool, industrial control, panelboard, and general-purpose applica-tions. These designs are now welded core and encapsulated to provide the highest quality electrical performance. The trans-former coil is completely surrounded by epoxy, making the unitimpervious to external elements. The lamination core is welded toprovide superior quiet performance.
Several types of terminations are available to simplify installation.These include primary and secondary leads out, integral fuse,and spade-type terminals and our standard which is a touchproof terminal block. Consult your local GE Sales Office for

Factory- or Field-Installed OptionsSecondary Fusing—Factory- or field-installed secondary fuseclips are available. They are restricted to units with terminal stripsand a single secondary voltage or secondary with one tap.
Dual Primary and Secondary Fusing—Factory- or field-installeddual primary and secondary fusing is available on all units, includ-ing leads out and multiple secondary voltages.
Leads Out—Terminal strip is replaced by rugged primary and secondary leads emanating from the top of the encapsulated coil.

CE-Rated
ApplicationThe compliant transformer offering developed by GE is of thehighest quality. This product is designed to be incorporated intoequipment manufactured for sale in the European Community.This product is in conformity with the European Standard: EN 60742, 1995 per the provisions of the Low Voltage (LV) Directive73/23/EEC in 1973 as amended by 93/68/EEC in 1995.
The Type “IP” offering utilizes all copper windings, which are encapsulated in a hardened epoxy, making the windingimpervious to the elements. These designs are rated at 55° C risewith a 40° C ambient. Standard on these designs are touch-proofterminal boards. These provide protection from current carryingterminals for personnel working on the equipment. These designsincorporate customer friendly connection on rugged high-impactmolded terminal boards. Besides being rated, these designsare both UL and C-UL listed.

The complete family of transformers from GE provide quiet, reliable transformer operation.
All of the dry-type transformers through 1,000 kVA are UL listedunder the requirements of Standard 506 and 1561. In addition,each transformer meets the requirements of NEMA ST-20, 1992.Type QB, QMS, and QMS 3 models are C-UL listed.
General-purpose transformers are rated 600 Volts and below for supplying appliance, lighting, and power loads from electricaldistribution systems. Standard distribution voltages are 600, 480,and 240 Volts; standard load voltages are 480, 240, 208, and 120Volts. The transformer is used to obtain the load voltage from thedistribution voltage. Since no vaults are required for installation,these transformers can be located right at the load to provide thecorrect voltage for the application. This eliminates the need forlong, costly, low-voltage feeders.
Construction—Types QB, QMS, and QMS 3
Core and coils are contained within a NEMA 3R nonventilatedweatherproof enclosure. Type QB, QMS, and QMS 3 units featureencapsulated core and coils.
Type QB, .050 kVA-3 kVA, Single-Phase
