<p>The present disclosure relates to a thermo magnetic circuit breaker that incorporates an indication mechanism to indicate cause of occurrence of a fault that tripped the circuit breaker. In an embodiment the indication is by means of a flag configured to pop out every time a short circuit fault occurs. On the other hand, there is no indication when the tripping takes place due to overload current thus enabling the user to differentiate between the two occurrences and act accordingly to attend to the fault. In an embodiment, the indication mechanism is configured to prevent resetting of the circuit breaker with flag in popped out position. The circuit breaker is permitted to be reset only after the flag has been brought back to its original position manually. Thus the user is prevented from resetting the circuit breaker immediately and the user is prompted to look for fault and remedy them before resuming the operation.</p> |
