摘要

The invention disclosed is a circuit breaker 2, comprising a case 3 that houses circuit breaker components 16, 20, 22. The case has a handle opening 7 for an operating handle 4 to project through the handle opening. The handle opening has a viewing cut-out 6 formed on a side of the handle opening. An operating handle 4 is pivotally 10 mounted inside the case, with an outer portion 17 extending through the handle opening in the case. The operating handle is operatively coupled to a contact operating mechanism 20 and a current-responsive tripping mechanism 22 in the case. An indicator 8 is positioned on a side 9 of the operating handle. The indicator is visible through the viewing cut-out when the operating handle has been moved to a central position (Fig. 3C) in the handle opening, in response to a trip event in the circuit breaker.
