Scope of application
The CJX2-N (LC2-D) series mechanical interlocking contactor (hereinafter referred to as the mechanical interlocking contactor) is assembled by adding a mechanical interlocking mechanism on the basis of the LC1-D series AC contactor. It is suitable for circuits with AC 50 or 60Hz, voltage up to 660V and below, and current up to 80A and below, for remote direct control of the starting, stopping, and reversible operation of three-phase squirrel cage motors. It has a mechanical interlocking mechanism that can ensure the safe operation of two reverse contacts and prevent short circuit accidents. Contactors with JRS1 series thermal relays can provide overload protection for electric motors.

This series of contact products comply with IEC947-4-1, GB14048.4, and JB/T7435 standards.
