Claims

[Scope of utility model registration request]

A normally open movable contact having a spring property and conductivity is driven by the cross bar and is opposed to the normally open movable contact, which has a crossbar engaged with a reversing movable part of a normally closed contact that operates in reverse. In a thermal overcurrent interrupter equipped with a contact mechanism that configures a normally open contact by energizing a normally open fixed contact, the contact between the projecting piece of the crossbar and the normally open movable contact in the reset state is provided. A thermal overcurrent relay characterized by having an air gap.
