AI Technical Summary
Existing integrated residual current circuit breakers have limited internal space and a single standard value for rated residual operating current, resulting in poor versatility and loss of protection function when the DIP switch fails.
Design an integrated residual current circuit breaker with switchable leakage current, using a DIP switch and a circuit board. The circuit board has two parallel circuits with two standard values of rated residual operating current. The rated residual operating current can be switched by the DIP switch, and at least one circuit can be kept in normal operation when the DIP switch fails.
It achieves switchable rated residual operating current standard value on the basis of miniaturization, adapts to complex terminal environment, ensures normal use of circuit breaker, avoids loss of protection function due to DIP switch failure, and facilitates user operation.
