Main Functions

1. Three-phase Motor On/Off Switching

    

   Carry rated motor starting and running current, control fans, pumps, conveyors, compressors and other AC induction motors; form complete motor starter combination with AB 193/592 thermal overload relays.
2. Heavy Inductive Load Control

    

   Suitable for switching large heaters, transformers, resistance furnaces under AC-1 resistive load mode up to 100A continuous current.
3. Expandable Auxiliary Signal Logic

    

   No built-in auxiliary contacts; install front/side-mounted auxiliary contact blocks (100-CAX series) to add NO/NC auxiliary contacts for PLC feedback, interlock and alarm signals.
4. Stable Anti-arc & Long Service Life

    

   Silver alloy main contacts suppress switching arc erosion; optimized magnetic arc extinguishing structure extends contact lifespan for frequent start-stop cycles.
5. Reversible Coil Wiring Design

    

   Coil terminals support wiring from line or load side, flexible cabinet wiring layout without extra wire rerouting.
6. Finger-Safe Safety Housing

    

   Fully shrouded power terminals prevent accidental electric shock during maintenance, meeting global machine safety requirements.
