ABSTRACT:
In a circuit breaker static trip unit, multiple targets are utilized to indicate which of several possible abnormal current conditions was responsible for precipitating tripping of the breaker contacts to interrupt a distribution circuit. The targets are selectively activated via a common target circuit which includes its own power supply. The target circuit is fail-safe in that failure or malfunction thereof cannot jeopardize tripping of the breaker contacts. Appropriate clamping is utilized to insure that only the selected target is activated.
