Model meaning

Product performance

1. The transfer switch is composed of two 63-type circuit breakers combined with the motor and mechanical interlocking device. The two power supplies are monitored by the controller. When the circuit is deviated, the controller makes a logical judgment on the monitoring result. The command drive motor drives the operating mechanism to open or close, thus ensuring safe and reliable power supply to the load.
