Tips: Does the leakage circuit breaker be able to use the down line?
The terminal line above the leakage circuit breaker is usually called the power supply, and the terminal terminal is usually called the load end. Can the power be connected to the load end, and the load is connected to the power supply? No way. Because at the present stage, the most widely used electric shock protection field is the electronic leakage circuit breaker. Because the tripping coil of the electronic leakage circuit breaker is transient charged only when the action signal is received. When the leakage circuit breaker divides the circuit, the tripping coil is immediately cut off. If the circuit of the leakage circuit breaker is connected with the down line, the voltage will still be added to the release coil after the action of the leakage circuit breaker, which will destroy the coil and make the whole leakage circuit breaker lose the leakage protection function.
6 amp current rating miniature circuit breaker with 6kA excellent breaking capability for its compact size, is designed for the short circuit and overload protection in the AC 50Hz circuit, 230/400V 3 pole voltage.
