Product Advantage
The operating voltage of the shunt circuit breaker with delay is any value in the range of 70%-110% of the rated voltage;
A control voltage. i.e. electricity (which can be supplied by a remote control line or IC card meter) is applied to the release pole and the breaker handle is pushed to the closed position to close. When the need for remote control (or lC card meter arrears) can be disconnected through the control system. The circuit breaker can be reliably broken at 0.5s≤t≤2s, and the circuit breaker also has short circuit and overload functions. When wiring, be sure to pay attention to the power line up and down, live wire, neutral wire polarity is correct.
