Frequently Asked Questions

What is an EATON NEMA reversing magnetic contactor used for?

An EATON NEMA reversing magnetic contactor controls motor direction in industrial applications such as conveyors, hoists, and pumps. It switches three-phase power to reverse rotation, commonly used in material handling and manufacturing lines where bidirectional motor control is required.

What are the specifications of the EATON CN55BN3BB contactor?

The EATON CN55BN3BB is a reversing NEMA magnetic contactor with 3 poles, NEMA Size 0, rated 18 A at 240V AC. It is designed for motor control applications requiring forward/reverse operation. 3G Electric supplies this genuine EATON part globally.

Where to buy the EATON CN55BN3BB contactor worldwide?

3G Electric supplies the EATON CN55BN3BB reversing contactor to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time; we source genuine EATON industrial controls for global procurement.

How to select the right NEMA contactor size for a motor?

Select a NEMA contactor size based on motor full-load current and voltage. For a 240V AC motor drawing 18 A, NEMA Size 0 (like the EATON CN55BN3BB) is appropriate. Always verify the contactor's continuous current rating exceeds motor FLA and that coil voltage matches your control circuit.
