ABSTRACT:
A system displays information from and controls electrical switching apparatus, such as circuit breakers. The system includes a plurality of circuit breakers having separable contacts and a plurality of conditions, such as bus temperature and contact wear. A plurality of sensors are structured to sense the conditions of the circuit breakers and to communicate the sensed conditions over corresponding wireless signals. A display and control unit is operatively associated with the circuit breakers and is structured to receive the corresponding wireless signals and display information corresponding to the sensed conditions or to control the circuit breakers based upon one or more of the sensed conditions.
