<p>An apparatus (300) of modular trip mechanism and auxiliary mechanism for a circuit breaker (100) comprises an auxiliary mechanism module (330) including a first micro switch (332) to output an electrical signal indicating an ON/OFF position of the circuit breaker, a first shaft contact lever mechanism (335M) to operate the first micro switch by contacting the switching shaft or receiving an artificial pressing force, a second micro switch (331) to output an electrical signal indicating whether a trip operation of the circuit breaker has been performed, and a second lever (336) to operate the second micro switch by contacting the switching shaft (500) or receiving an artificial pressing force; and a trip mechanism module (310) including an electromagnetic trip device (321) to operate a trip bar to trigger the circuit breaker to a trip position in response to a trip control signal from an overcurrent relay or a test trip control signal from a test signal generating source.</p> |
