Slow trip breaker
WebbPreventing slow Circuit Breaker Trip: the challenge for asset managers. A slow circuit breaker trip, due to aging or poor maintenance can cause major problems for network operators, taking customers off supply. And a delay in the circuit breaker trip can cause high current faults to ‘cascade’ across the network, leading to: Plant damage Webb30 juli 2024 · 2. Ideally, a circuit breaker should never trip while carrying its rated current. Looking further down the graph to where it should trip, we find that a 30 Amp breaker will trip in about 10 seconds if carrying 60 Amps (200% of rating). A short pulse of 200% overload (say, 5 seconds) will not cause a trip, but a continuous 200% overload will ...
