Claims

[Claims for Utility Model Registration] (1) A pair of shield breaker contacts, an operating electromagnet that is energized by a remote control signal to open and close the shield breaker contacts, and a remote control circuit for this operating electromagnet. a switch for disconnecting the circuit at the time of trip, which is disposed close to the operating electromagnet and constituting a remote control circuit for the operating electromagnet; a switch base that holds the switch, a diode that is disposed on the switch base and constitutes a remote control circuit for the operation electromagnet, and a device that connects both the switches via the diode, and a An inter-switch lead wire with a conductor exposed on the part that is fixed, and a terminal connection lead that connects the trip circuit disconnection switch to a remote control circuit terminal and has a conductor exposed on the part that is fixed to the switch. In a remote-controlled circuit breaker having a wire, the switch base includes:
a first protrusion that insulates the exposed conductor of the inter-switch lead wire and the lead of the diode from the yoke of the operating electromagnet; A remote control type circuit breaker characterized in that a second protrusion is provided to insulate the exposed conductor of the terminal connection lead wire. (2) A remote-controlled circuit breaker according to claim 1, wherein the first protrusion and the second protrusion are integrally molded on the switch base from an electrically insulating material.
