Document Type and Number:
WIPO Patent Application WO/2019/038813
Kind Code:
A1
Abstract:
In this invention, a fixed iron core (61) of an electromagnetic operating mechanism (60) comprises: a first divided iron core (81) and a second divided iron core (82) each formed from a stack of a plurality of magnetic plates (90); and a first linking member (83), a second linking member (84), a third linking member (85), and a fourth linking member (86) each comprising a magnetic plate (91). The magnetic plate (91) has an identical shape to that of the magnetic plates (90), and links the first divided iron core (81) to the second divided iron core (82) while being oriented differently from the magnetic plates (90). Each magnetic plate (91) has a fixing region to be fixed to a support part provided in a circuit breaker casing, said fixing region protruding to the outer side of at least one from among the first divided iron core (81) and the second divided iron core (82) in an orthogonal direction to the stacking direction of the plurality of magnetic plates (90) comprised in the first divided iron core (81) and the second divided iron core (82).
