More Information
Summary:CIRCUIT BREAKER TEST KIT A test kit for a digital and analog electronic circuit breaker determines the calibration and overcurrent response of the circuit breaker when connected within an electric power circuit. The test kit simulates an overcurrent condition and provides verification of the circuit breaker response without de-energizing the circuit breaker or interfering with the circuit breaker's protection functions. The test kit connects with the digital communications circuit within the digital circuit breaker to obtain status information concerning pick-up conditions, trip conditions and fault currents which are viewed on the test kit liquid crystal display. A ground fault suppression circuit is included within the test kit for single-phase current-injection without causing ground fault tripping. The test kit circuit further includes means for optionally tripping the circuit breaker upon completion of any of the tests.
