Mechanism of thermomagnetic formula moulded case circuit breaker's demonstration circuit fault type

The utility model relates to a mechanism of thermomagnetic formula moulded case circuit breaker's demonstration circuit fault type, include: magnetism release lever, hot release lever and coaxial, magnetism release lever and hot release lever are worn simultaneously in the coaxial, the action mutually noninterfere. The utility model discloses well instruction state is opened on the lid and is indicateed the window by indicateing the window to realize, is gone into to indicate the corresponding disengaging state of windows display with the indicator bullet by the spring when appearing threading off, presses the home position with indicator again when the handle restores to the throne. Ratchet, detent mechanism are adopted in hot release lever, magnetism release lever and corresponding indicator's hasp and dropout. Indicator sets up and sets up to the pawl for driving ratchet, release lever. The indicator ratchet sets up an expanding spring, makes the indicator ratchet rotate certain angle around the ratchet ce
