Features:

 

SYA-4000 circuit breaker is suitable for frequency: 50 ~ 60Hz, voltage: 400 ~ 690V power grid, mainly used for power distribution, feed or motor protection, to protect lines and power equipment from overload, grounding/leakage, current imbalance, over The hazards of voltage, undervoltage, voltage imbalance, over-frequency, under-frequency, reverse power and other faults; under normal conditions, it can be used for infrequent conversion of lines, and can also be used for infrequent starting and protection of motors. When the power network performs communication networking, the controller can use remote terminals of the power automation network to achieve different networking requirements such as telemetry, remote control, remote signaling, and remote adjustment. The circuit breaker has an isolation function.
