1. Application

Chint CJX1-K series AC vacuum contactors (hereinafter referred to as contactors) are mainly suitable to be used in the circuit with AC 50Hz~60Hz, rated working voltage up to 1000V, and rated working current up to 820A, for remote connection and disconnection of circuits. The contactors can be used in combination with appropriate thermal overload relay or electronic protector and other
protective devices to form a vacuum electromagnetic starter, especially suitable for forming an explosion-proof vacuum electromagnetic starter. The contactors are widely applied in mines, smelting, petroleum extraction, storage, chemical industry, military industry, textile, construction and other flammable, explosive or harsh environment.
Compliance standards: IEC 60947-4-1.

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.
