However, there is currently no circuit breaker trip indicating device that can indicate the three breaking states of short-circuit fault, overload fault and artificial disconnection, so when the circuit breaker (especially the household circuit breaker) trips, the user often cannot Knowing the exact cause of failure makes troubleshooting a major challenge

The invention discloses a trip indication system and a circuit breaker for a circuit breaker. The trip indication system comprises: a magnetic trip link rotatably fixed on the shaft of the trip actuator of the circuit breaker; a first fault indication marking area exposed by a first window on the housing of the circuit breaker; and a second trip indicator arranged side by side with the first trip indicator, having a protrusion, and having a A second fault indication marking area exposed through a second window on the housing of the circuit breaker. When the circuit breaker is magnetically tripped, the first and second fault indication mark areas are revealed, and when the circuit breaker is thermally tripped, only the first fault indication mark area is revealed, while the second fault indication mark area is not revealed. According to the present invention, short-circuit fault, overload fault and artificial disconnection can be clearly indicated.
Description
technical field [0001] The invention relates to a circuit breaker trip indication device and a circuit breaker with the circuit breaker trip indication device. Background technique [0002] Existing miniature circuit breakers generally have short-circuit and overload protection functions. Once a short-circuit or overload occurs, the circuit breaker will trip, but at this time users often cannot determine whether a short-circuit or an overload has occurred (unless the large short-circuit current is broken. , the outer casing will be visibly polluted). It makes sense for the user to know exactly whether a short circuit or an overload has occurred. If it is overload, you can cut off part of the electrical equipment on this branch, and then turn on the switch to use it normally; but if it is a short circuit fault, you must find the short circuit point, and then close the circuit breaker after troubleshooting, or replace the circuit breaker immediately device.
