It incorporates an AS-i (Actuator Sensor Interface) communication module for seamless integration into automated systems. This assembly is rated for AC-3 duty, making it suitable for standard motor starting applications with a power rating of 75 kW at 400 V. The control voltage is versatile, accepting both 20-33 V AC and DC. It features a Size S3 contactor, utilizing screw terminals for secure and reliable electrical connections. Mechanical and electrical interlocks are included to prevent short circuits and ensure safe operation.

An integrated varistor provides surge protection, safeguarding the contactor from voltage spikes. This pre-wired assembly simplifies installation and reduces wiring errors, saving time and cost.
