Product description

General-purpose soft-start control cabinet is based on domestic brand soft starter or imported brand soft starter as the main control element and is equipped with main circuit incoming circuit breaker and bypass contactor. It has short-circuit protection, overload protection, over-current and input shortage. Phase, output phase failure protection function. Control device for single motor or multiple motors that can realize multiple protection. Including universal type, 1 tow 2, 1 tow 3, 1 tow 4, life pump 1 with 1 standby, dual-use 1 standby soft start cabinet. The soft starter can be configured with Chinese brand or imported brand Schneider, ABB, Siemens and other series soft starters.


● Starting performance is far superior to frequency sensitive varistor, oil immersed varistor, cast iron resistance and other starters;

● Soft start, the starting current is small, about 1.3 times the rated current of the motor;

● Can be started continuously 5-10 times;

● The starting process is smooth, no mechanical stress impact on the equipment, which can extend the life of the mechanical equipment and electricity;

● It can be started with low voltage, when the grid voltage is lower than 10% of the rated voltage of the motor, it can be started smoothly;

● Wide applicability, can be applied to the soft start of the winding motor under any load condition, especially suitable for heavy load start;

● It has multiple protection functions such as start timeout, pressure loss, over-travel, over-temperature, etc .;

● Automatic heating function in cold areas;
