Fire-control box for cut electricity

PXJ starting control box is composed of circuit breaker, AC contactor, thermal relay, button, indicator light, voltmeter, ammeter, etc. The star connection method is adopted to reduce the winding voltage when the motor is started. After starting, the motor is switched to the triangle connection method. The motor is started in a reduced voltage mode with normal voltage operation. This method can effectively reduce the starting current and protect the motor from burning.

It is suitable for infrequent start and stop control of various types of fans with large load of 11kw ~ 110kW and long start time. Such as 4-72, Y5-47, C6-46 large inertia centrifugal fan, Roots fan, etc.
