Claims

[Scope of utility model registration request]

A display button and an elastic body that applies an elastic force to the display button in an outward direction of the case are provided near the electrical contacts in a case housing at least one pair of electrical contacts that can be separated from each other; A circuit breaker characterized in that a tension member is installed at a position within the case where the arc is received, the tension member is attached to the case to pull the display button inward against the elastic force, and to melt when receiving the heat of the arc. .
