PURPOSE: A forcible trip device of a small-size circuit breaker is provided to improve reliability of a circuit breaker by urgently operating a circuit breaker if necessary after installing a circuit breaker in a circuit. CONSTITUTION: A fixing bar(20) is installed in a lower end of a case(10). A movable bar(30) turns on/off a circuit by being selectively contacted with the fixing bar. A handle(40) manually turns on/off the movable bar. A trip bar(70) operates a latch to a restriction position or a release position. A forcible trip unit(100) is installed in the case and arbitrarily operates the trip bar.
