Abstract (en)
[origin: EP4266343A1] To obtain an overcurrent trip device which can realize a reduction in the size of the device and a circuit breaker using the same. An overcurrent trip device (100) includes a conductor (3) connected to a main circuit of a circuit breaker (200); a stationary core (1) which is formed so as to enclose the conductor (3) and one portion of which is opened; and a moving core (2) which is disposed in the opened position of the stationary core (1) with a magnetic gap (4) interposed between the moving core and the stationary core (1), is disposed so as to be movable by an electromagnetic force of when an overcurrent flows through the conductor (3), wherein the stationary core (1) is disposed in abutment with the conductor (3), and the moving core (2) is in contact with the conductor (3) when no overcurrent flows through the conductor (3) before in operation.
