TRIPPING UNIT FOR CIRCUIT BREAKER |
摘要 |
A tripping unit is configured to send an electrical tripping-signal to a switching unit of a circuit breaker so as to trip main contacts of main circuits of the circuit breaker in response to a detection of a current being above a predetermined level in at least one of the main circuits. The tripping unit includes a fuse configured to be connected in series to a main circuit of the circuit breaker and a detection unit connected in parallel with the fuse and configured to generate the tripping signal for the switching unit in response to the fuse being blown. |
