Abstract
A circuit breaker has a thermally sensitive bimetal connected across two lead-in wires in a glass envelope. An electrically conductive bypass element is in parallel with the bimetal and shorts it out. The bypass element can be removed from the circuit by melting it by means of a short duration pulse of high electric current. The bimetal contains means to prevent its ends from welding together should an arc occur when the bypass element is melted.
