Frequently Asked Questions

Q: How do I select the right contactor size for my motor?

A: The contactor should be rated for at least the motor's full load current (FLC). For AC-3 duty, use the motor's rated current. For heavy start applications, consider the next size up.

Q: Do I need an overload relay with this contactor?

A: Yes, a contactor provides switching control but does NOT protect against motor overload. You need a thermal overload relay (such as Chint NR2/NXR series) mounted directly below the contactor.
