Mechanical wear, wipe and stroke measurement system for circuit breakers
Abstract:
A contact wear indicator assembly for a circuit breaker assembly is provided. The contact wear indicator assembly includes an interface assembly, an indicator drive assembly, and a user display assembly. The user display assembly includes an output device. The output device is structured to produce a visual indication representative of a measurable contact characteristic. The indicator drive assembly is operatively coupled to the interface assembly, whereby the indicator drive assembly moves between a first position and a second position corresponding to an interface assembly first and second position. The indicator drive assembly is measurably coupled to the user display assembly. The user display assembly is structured to convert the position data of the indicator drive assembly into a quantified output such as, but not limited to, contact characteristics. The user display assembly is further structured to display the indicator drive assembly position data on the output device.
