The working power of the residual current protection circuit of this series of circuit breakers is supplied by the multi-phase power supply (the working power of the protection circuit of early products is supplied by the single-phase power supply)the residual current protection circuit of the device can still operate normally.When the operating power voltage of the circuit breaker’s residual current protection circuit is reduced to 50V, the circuit breaker’s residual current protection circuit can still work normally.(I coherence n=30mA)
This series of circuit breakers are classified into B type (i.e., basic breaking capacity) (Inm less than 100), S type (i.e., standard breaking capacity) and H type (i.e High score breaking capacity (Inm > 160) can be used in different situations.
The main circuit of a circuit breaker is connected in many ways:
Piston front connection
Terminal extension plate front connection
The screw connection at the rear of the piston plate
