Abstract: A trip control circuit for a circuit breaker which provides for self-diagnostics includes a normally opened trip contact, a tripping circuit, and a signal light in series with the tripping circuit and the trip contact. The trip control circuit also includes a flasher circuit constructed and arranged to provide signaling of an abnormal condition of a circuit breaker to the signal light, while permitting the circuit breaker to trip provided that a cause of the abnormal condition signaled is not one which prevents tripping of the circuit breaker.
Abstract translation: 提供自诊断功能的断路器跳闸控制电路包括常开触发触发，跳闸电路以及与跳闸触点串联的信号光。 跳闸控制电路还包括闪络器电路，其构造和布置成向断路器的信号灯提供异常状态的信号，同时允许断路器跳闸，只要发出异常状态的原因不是防止跳闸的原因 的断路器。
