Frequently Asked Questions

What is the EATON CN55DN3BB reversing magnetic contactor used for?

The EATON CN55DN3BB is a reversing NEMA magnetic contactor used to control the direction of three-phase motors in industrial applications such as conveyors, hoists, and pumps. It switches motor rotation by alternating phase connections, enabling forward and reverse operation in manufacturing and material handling systems.

What are the specifications of the EATON CN55DN3BB contactor?

The EATON CN55DN3BB is a reversing NEMA magnetic contactor with 3 poles, NEMA Size 1, rated 27 A at 240V AC. It is designed for motor control and features a compact, rugged construction suitable for industrial environments. The manufacturer part number is CN55DN3BB.

Where to buy the EATON CN55DN3BB contactor worldwide?

You can source the EATON CN55DN3BB reversing contactor through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide reliable sourcing for this EATON component.

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

Select a NEMA contactor by matching its size and current rating to the motor full-load amps and voltage. For reversing applications, ensure the contactor is rated for forward/reverse duty. The EATON CN55DN3BB, NEMA Size 1 at 27 A, suits motors up to that load. Always verify coil voltage (240V AC) and enclosure requirements per NEC guidelines.
