Frequently Asked Questions

What is the EATON CN15KN3B NEMA magnetic contactor used for?

The EATON CN15KN3B is a non-reversing NEMA magnetic contactor used to switch motor loads and other inductive loads in industrial control panels, HVAC systems, and pump stations. It handles high inrush currents and provides reliable on/off control for three-phase equipment up to 90 A at 240V AC.

What are the specifications of the EATON CN15KN3B contactor?

The EATON CN15KN3B is a NEMA Size 3, non-reversing contactor with 3 poles rated at 90 A continuous current and 240V AC coil voltage. It is designed for heavy-duty motor starting and switching applications in industrial environments, meeting NEMA standards for durability and performance.

Where to buy the EATON CN15KN3B contactor worldwide?

3G Electric supplies the EATON CN15KN3B contactor worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this NEMA Size 3, 90 A, 240V AC magnetic contactor.

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

Select a NEMA contactor size based on the motor's full-load current and voltage. For a 90 A, 240V AC motor, a NEMA Size 3 contactor like the EATON CN15KN3B is appropriate. Always verify the contactor's continuous current rating exceeds the motor's FLA and consider inrush current during startup.
