<P>PROBLEM TO BE SOLVED: To provide an apparatus of modular trip mechanism and auxiliary mechanism for a circuit breaker which can be tested before being assembled. <P>SOLUTION: The apparatus of modular trip mechanism and auxiliary mechanism comprises: an auxiliary mechanism module 330 including a first micro switch 332 to output a signal indicating an ON position or OFF position of a circuit breaker 1000, a first shaft contact lever mechanism 335M to operate the first micro switch 332 by contacting with a switching shaft 500 or receiving a pressing force for test, a second micro switch 331 to output a signal indicating whether the circuit breaker 1000 performs a trip operation, and a second lever 336 to operate the second micro switch 331 by contacting with the switching shaft 500 or receiving a pressing force for test; and a trip mechanism module 310 including a trip bar 313a and an electromagnetic trip mechanism 321 to operate the trip bar 313a to a position to trigger the circuit breaker 1000 to a trip position in response to a trip control signal from an overcurrent relay 200 or a test trip control signal from a test signal generating source. <P>COPYRIGHT: (C)2013,JPO&INPIT |
