Abstract:
A circuit breaker comprising:a first connecting terminal and a second connecting terminal; a heating portion movably disposed in electrical contact with and between the first connecting terminal and the second connecting terminal, the heating portion charged with a heating agent; an igniting portion for igniting the heating agent charged in the heating portion; an outer case accommodating the ignition portion and the heating portion; and an extendable resilient member mounted to a removable member in a compressed state, the removable member being configured to removably engage with the outer case such that when the removable member is engaged with the outer case, the removable member is located in the vicinity of the heating portion, whereby, upon ignition of the heating agent, the extendable resilient member extends from the compressed state, exerting force onto the heating portion to move the heating portion from the contact position, such that the electrical connection between the heating portion and the first and second connecting terminals is interrupted.
