Title: Circuit breaker
Inventor: MORIWAKI HIDEAKI
IPC: H01H71/40
Filed: 1988-03-23
Abstract: PURPOSE:To make it possible to select the capacity of a heating resistance and the value of the resistance at will without considering the current limit at the time of short circuit by employing a short circuit device for short-circuiting the heating resistance when a circuit current caused by the electromagnetic force of an electromagnetic coil exceeds a specified value. CONSTITUTION:When an excessive current flows due to short circuit or the like on a load side, a movable iron core 204, resisting the force of a push spring 203, is attracted to the side of a fixed iron core 202 due to magnetic flux generated by a current flowing in an electromagnetic coil 201. As a rod 205 simultaneously moves downward, a movable conductor 701 connected to the rod 205 also descends to close both contact points 702 and 704. As a result, a new current passage is formed from a support plate 503, a fixed contact point 704, a movable contact point 702, a movable conductor 701, the movable contact point 702, the fixed contact point 704, a fixed conductor 703, a shunt 705, an electromagnetic coil 201, and to a load conductor 603. Namely, both ends of a heating resistance 101 are shorted with a short-circuit device 7 so that all the excessive current flows through the short circuit device 7 and does not flow through the heating resistance 101. As a result, the value of resistance can be selected at will.
