Frequently Asked Questions

What is the EATON CN55SN3B reversing magnetic contactor used for?

The EATON CN55SN3B is a reversing NEMA magnetic contactor used to control the forward and reverse rotation of three-phase AC motors in industrial applications such as conveyors, pumps, and hoists. It is designed for heavy-duty motor starting and switching in manufacturing, processing, and material-handling environments.

What are the specifications of the EATON CN55SN3B contactor?

The EATON CN55SN3B is a reversing NEMA magnetic contactor with 3 poles, NEMA Size 5, rated 270 A, and a coil voltage of 240V AC. It is manufactured by EATON under part number CN55SN3B. This contactor is suitable for high-current motor control applications requiring reversing functionality.

Where to buy the EATON CN55SN3B contactor worldwide?

You can source the EATON CN55SN3B reversing contactor through 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; we supply genuine EATON components for industrial motor control systems.

How to select the correct NEMA contactor for a motor application?

To select the correct NEMA contactor, match the contactor's NEMA size and continuous current rating to the motor's full-load current and duty cycle. For reversing applications, ensure the contactor is mechanically interlocked. The EATON CN55SN3B, rated 270 A at 240V AC, is suitable for large motors. Always verify coil voltage matches your control circuit.
