Frequently Asked Questions

What is the EATON CN55NN3B reversing magnetic contactor used for?

The EATON CN55NN3B reversing magnetic contactor is used to control the forward and reverse rotation of three-phase AC motors in industrial applications such as conveyors, hoists, and pumps. It is a NEMA Size 4, 3-pole device rated at 135 A and 240V AC, suitable for heavy-duty motor starting and reversing.

What are the specifications of the EATON CN55NN3B contactor?

The EATON CN55NN3B is a reversing NEMA magnetic contactor with 3 poles, NEMA Size 4, and a continuous current rating of 135 A. It operates at 240V AC coil voltage. The manufacturer part number is CN55NN3B. This EATON contactor is designed for reliable motor reversing in demanding industrial environments.

Where to buy the EATON CN55NN3B contactor worldwide?

You can source the EATON CN55NN3B reversing contactor from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for availability and lead time on this EATON part number.

How to select the correct EATON reversing contactor for a motor?

To select the correct EATON reversing contactor like the CN55NN3B, match the NEMA size and current rating to your motor's full-load amps and voltage. For a 135 A, 240V AC application, NEMA Size 4 is appropriate. Always verify coil voltage and pole configuration. Consult EATON's technical documentation for specific motor horsepower ratings.
