Working Principle

① Rated voltage energizes the coil to generate electromagnetic force and drive internal springs;

② Moving and static contacts close to switch on the load circuit;

③ The spring resets contacts to cut off the circuit once the coil is de-energized;

④ High voltage isolation enables low-voltage control for high-power loads and suppresses load surge;

⑤ It protects precision controllers like PLC and guarantees stable operation of emergency stop and protection loops.
