Abstract

A failure prediction assembly is structured to monitor circuit breaker assembly sub-assemblies and their component's characteristics. The failure prediction assembly includes a sensor supported D-shaft and a sensor assembly including a housing and a number of sensors. The sensor assembly housing defines a D-shaft passage. A control unit is in electronic communication with the sensor assembly. The sensor assembly housing is coupled to the circuit breaker sidewalls with the sensor assembly housing D-shaft passage aligned with the circuit breaker sidewall D-shaft passages. The sensor supported D-shaft is rotatably coupled to the sensor assembly with the sensor supported D-shaft disposed through said sensor assembly housing D-shaft passage.
