Understanding Time Current Curves - Maverick Technologies
www.mavtechglobal.comThis is due to tolerance of the trip elements in the circuit breaker. The curves below (Figures 12 and 13), will show the differences in this deadband for the same circuit breaker using an electronic versus non-electronic trip mechanism. Notice the difference in the tolerance in the trip curve of the feeder circuit breaker.
