EATON Freedom Series NEMA Contactors & Electric Motor Starters
NEMA Contactors—Non-Reversing and Reversing
Non-Reversing and Reversing Contactors
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, and so on.
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, Benefits and Functions;
- 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 ontactor for Sizes 00–8

Magnet Coils—AC or DC
Contactor coils listed in this section also have a 50 Hz rating as shown in the Coil Voltage Code section. Select required contactor by Part number and replace the magnet coil alpha designation in the part number (A) with the proper Coil Voltage Code.
For Sizes 00–2, the magnet coil alpha designation will be the next to the last digit of the listed Part number.
EXAMPLE: For a 380V, 50 Hz coil, change CN15AN3_B to CN15AN3LB. For all other sizes, the magnet coil alpha designation will be the last digit of the listed Part number.
