遮断器。[Scope of Claim for Utility Model Registration] (1) A short-circuit current detection section having a coil for detecting a short-circuit current, a bimetal for detecting an overcurrent as well as a short-circuit current flowing through the short-circuit current detection section, and a base end of the bimetal. The circuit is equipped with an overcurrent detection section consisting of a heater to which the above-mentioned coil is wound. In a circuit breaker where a heater is installed almost vertically adjacent to the circuit breaker, the circuit breaker is fixed to the base so as to resist the force applied to the heater due to the electromagnetic force generated when a short circuit current flows through the coil and heater. A circuit breaker characterized by being equipped with a fixing metal fitting. (2) The above-mentioned heater is formed in a U-shape with an open coil direction, and the utility model registration claim 1 is made by resisting the force applied to the heater due to the electromagnetic force generated when a short circuit current flows through the coil and the heater. The circuit breaker according to item 1.
