Product Description
feature a compact, space-saving design, using state-of-the-art technology and the latest in high strength, impact and temperature resistant insulating materials.
Straight-through wiring — line lugs
at top, load lugs at bottom.
Horizontal or vertical mounting
on upright panel for application freedom.
Screw type power terminals have
captive, backed-out self-lifting pres­sure plates with ± screws — reduced wiring time.
Accessible terminals for easy wir-
ing. Optional fingerproof shields available to prevent electrical shock.
Top located coil terminals conve-
nient and readily accessible. 45 mm contactor magnet coils have three terminals, permitting either top or diagonal wiring — easy to replace European or U.S. style starters or contactors without changing wiring layout.
Encapsulated dual voltage/
frequency magnet coils — permanently marked with voltage, frequency and part number. NEMA Sizes 00 – 0 have non-encapsulated coils as standard.
Designed to meet or exceed NEMA,
UL, CSA, VDE, BS and other interna­tional standards and listings.

ISO 9000 Certification
When you turn to Eaton’s Cutler­Hammer Products, you turn to quality. The International Standards Organiza­tion (ISO) has established a series of standards acknowledged by 91 indus­trialized nations to bring harmony to the international quest for quality. The ISO certification process covers 20 quality system elements in design, production and installation that must conform to achieve registration. This commitment to quality will result in increased product reliability and total customer satisfaction.
Short Circuit Protection
Fuses and Inverse-Time Circuit Breakers
may be selected per Article 430, Part D of the National Electrical Code to pro­tect motor branch circuits from fault conditions. If higher ratings or settings are required to start the motor, do not exceed the maximum as listed in Exception No. 2, Article 430-52.
Features
Freedom NEMA
Adjustable Bimetallic Ambient
Compensated Overload relays with interchangeable heater packs — available in three basic sizes, covering applications up to 900 hp — reducing the number of different contactor/overload relay combina­tions that have to be stocked. Fixed heater overloads are optional.
Electronic Solid-State Overload
Relay (C396) available as a stand­alone unit and assembled with Freedom Contactor.
A full line of snap-on accessories
common to both IEC and NEMA devices — top and side mounted auxiliary contacts, solid-state and pneumatic timers, etc.

NEMA Size 1 — Cat. No. CN15DN3AB
Product Description
Non-reversing
Contactors are most commonly used to switch motor loads in applications where running overcurrent protection is either not required or is provided separately. Contactors consist of a magnetically actuated switch which can be remotely operated by a push­button station or pilot device such as a proximity switch, limit switch, float switch, auxiliary contacts, etc.
NEMA Size 1 Cat. No. CN55DN3AB
Reversing
Reversing contactors are used prima­rily for reversing single- or three-phase motors in applications where running overcurrent protection is either not required or is provided separately. They consist of two contactors mechanically and electrically inter­locked to prevent line shorts and energization of both contactors simultaneously.
Features
Designed specifically for use in
applications requiring NEMA rat­ings. Contactors meet or exceed NEMA standards ICS 2-1993.
Long life twin break, silver cadmium
oxide contacts — provide excellent conductivity and superior resistance to welding and arc erosion.
Designed to 3,000,000 electrical
operations at maximum hp ratings up through 25 hp at 600V.
Steel mounting plate standard on all
open type contactors.
Non-reversing
Holding circuit contact(s) supplied
as standard:
Sizes 00 – 3 have NO auxiliary
contact block mounted on right hand side (on Size 00, contact occupies 4th power pole position — no increase in width).
Sizes 4 – 5 have a NO contact
block mounted on left side.
Sizes 6 – 7 have a 2NO/2NC
contact block on top left.
Size 8 has a NO/NC contact block
on top left back and a NO contact block on top right back.
Reversing
One NO-NC side mounted interlock
supplied as standard on each con­tactor for Sizes 00 – 8.
