Abstract (en)
A circuit breaker includes an L-pole circuit breaker (3, 6), an N-pole circuit breaker (4, 7) and a remote opening controller (5,8). An L-pole lock catch (31) and an N-pole lock catch (41) are connected through a lock catch shaft (32, 61). The N-pole lock catch (41) is provided with a socket (411) for realizing delayed tripping. One end of the lock catch shaft (32, 61) passing through the socket (411) on the N-pole lock catch (41), is connected and fitted with the remote opening controller (5,8), and another end of the lock catch shaft (32, 61) is connected and fitted with the L-pole lock catch (31). The shape of the socket (411) is configured to be capable of accommodating the lock catch shaft (32, 61) to abut against the socket (411) after the lock catch shaft (32, 61) conducts a certain movement stroke.
