● Core Function: Enables safe control of high-voltage, high-current main circuits using low-voltage, low-current control circuits.

● High Operating Frequency: Capable of frequent operation (e.g., hundreds to thousands of times per hour), suitable for equipment requiring frequent start/stop.

● Undervoltage/No-voltage Protection: Automatically disconnects when supply voltage is too low or lost, preventing motor burnout from running under low voltage. Does not re-engage automatically upon voltage recovery, preventing unexpected starts for safety.

● Enables Remote and Automatic Control: Easily controlled by push buttons, relays, PLC output points, etc.

● Lacks Intrinsic Short-Circuit and Overload Protection: Must be used in conjunction with fuses (short-circuit protection) and thermal overload relays (overload protection) to form a complete motor control circuit.
