Product DescriptionThe "Freedom Series" starters featurea compact, space-saving design, usingstate-of-the-art technology and thelatest in high strength, impact andtemperature resistant insulatingmaterials. Starters are available in tworating/configuration styles — NEMA(National Electrical ManufacturersAssociation) and IEC (InternationalElectrotechnical Commission). TheNEMA devices are sized based ontraditional NEMA classifications andthe IEC devices on internationalratings. Internationally rated starters,as compared to NEMA devices,generally are physically down-sized toprovide higher ratings in a smallerpackage. However, electrical load/liferatings are correspondingly reduced.
Careful consideration should be givento the selection of the proper devicefor a specific application. Parameters,such as type of load, severity of duty,electrical load/life cycles required, etc.,must be evaluated before choosingeither the IEC or NEMA designs. Sincethe IEC devices are typically smallerthan the equivalent NEMA device,there is a cost advantage over theNEMA starters and contactors.
Features• A single family of starters suitable
for application in both the IEC andNEMA markets. "Two lines, Onefamily" — the best of both worlds.
• Adjustable Bimetallic AmbientCompensated Overload Relays withinterchangeable heater packs —available in three basic sizes,covering applications up to 900 hp— reducing the number of differentcontactor/overload relay combi-nations that have to be stocked.Fixed heater overloads optional.
• A full line of snap-on accessoriescommon to both IEC and NEMAdevices — top and side mountedauxiliary contacts, solid-state andpneumatic timers, etc.
• Straight-through wiring — line lugsat top, load lugs at bottom.
• Horizontal or vertical mounting on•^-^upright panel for application freedom.
• Screw type power terminals havecaptive, backed-out self-liftingpressure plates with ± screws —reduced wiring time.
• Accessible terminals for easywiring. Optional fingerproof shieldsavailable to prevent electrical shock.
• Top located coil terminalsconvenient and readily accessible.45 mm contactor magnet coils havethree terminals, permitting eithertop or diagonal wiring — easy toreplace European or U.S. stylestarters or contactors withoutchanging wiring layout.
• Encapsulated dual voltage/frequency magnet coils — perma-nently marked with voltage, fre-quency and part number. IEC sizes A- F have non-encapsulated coils asstandard, encapsulated as optional.
• Designed to meet or exceed NEMA,•̂""UL, CSA, IEC, VDE, BS and other
international standards and listings.• American engineering and manu-
facturing — built in the U.S.A. byEaton Corp./Cutler-Hammer, usingthe latest in statistical processcontrol methods to produce highquality, reliable products.
Standards and CertificationsCertified Type 2 CoordinationCutler-Hammer Freedom Series IECstarters and NEMA starters are ULCertified to achieve IEC 947 Type 2coordination against 100,OOOA shortcircuit fault currents. Any brand ofproperly selected fuse can be used.Type 2 coordination means that thestarter will be suitable for further usefollowing a short circuit fault.
ISO 9001 CertificationWhen you turn to Cutler-HammerProducts, you turn to quality. TheInternational Standards Organization(ISO) has established a series ofstandards acknowledged by 91industrialized nations to bring harmonyto the international quest for quality.The ISO certification process covers 20quality system elements in design,production and installation that mustconform to achieve registration. TheEnclosed Control is manufactured inour Fayetteville, NC plant, and thisfacility is registered ISO 9001. Thiscommitment to quality results inincreased product reliability and totalcustomer satisfaction.
Freedom NEMA starters are designedto NEMA standards and are extremelyrugged products built for any applica-tion. Their long electrical/mechanicallife is extended through easymaintainability.
• Meets and exceeds all NEMA, UL^--and CSA standards.
• Sized based on standard NEMAclassifications.
• Designed and built for a variety ofdemanding applications.
• Easy coil change and inspectable/replaceable contacts.
• Adjustable/interchangeable heaterpacks for flexibility.
•^Available Open and in NEMA 1, 3R,•̂̂ 4/4X, 7/9 and 12 enclosures.
Short Circuit ProtectionFuses and Inverse-Time Circuit Break-ers may be selected per Article 430,Part D of the National Electrical Codeto protect motor branch circuits fromfault conditions. If higher ratings orsettings are required to start themotor, do not exceed the maximumas listed in Exception No. 2, Article430-52.
