Soft Starter Control Panel

CHZIRI Electrical can design different soft starter Control panel according to clients'wiring diagram . Welcome to send inquiry to us .


Clicks: 7037

ZJRG  series soft starter control panel is suitable for three-phase AC squirrel cage induction motors. The control panel is mainly composed of a soft starter, AC contactor (bypass) and circuit breaker (short circuit protection). Have the function of protecting the motor improvement in motor starting and running process; adopt closed-loop control, greatly improving the stability and reliability of soft torque start and soft torque stop, run by the bypass contactor, the power consumption is close to zero.
