YCQR7-G Soft start control cabinet

Product Detail

General

The YCQR7-G soft starter control cabinet is used in situations where a motor is running.The control cabinet contains a soft starter primarily used for the smooth start of the motor,avoiding the impact and pressure during startup. It is typically employed in scenarios with large motors or where frequent starting and stopping is required, extending the motor’s lifespan and enhancing system stability. Soft starter cabinets are widely used in industrial sectors, energy fields, mining, and other heavy-duty equipment applications.
