circuit breaker timer is a testing tool used to determine if the circuit breaker is still in good working condition. One of the most common tools used is the Doble TR3100. It accurately measures the travel time of the contacts from closed to open, the velocity of the contacts when it trips, grading capacitor values and insertions resistor values. It displays the test results through its LCD screen and you can also print out the results using its built-in thermal printer.
