Circuit breaker characteristics
WebCircuit Breaker 14 #12 Conductor Copper THW Damage Curve Insulation Footnote 1: Transformer damage curves indicate when it will be damaged, thermally and/or mechanically, under overcurrent conditions. Transformer impedance, as well as primary and secondary connections, and type, all will determine their damage characteristics. WebIt tells us that at 1.5X the rated current the quickest the circuit breaker will trip is forty seconds (1). Forty seconds at 2X the rated current is the slowest the circuit breaker will trip (2). The bottom of the chart is for the magnetic trip of the coil/solenoid; 0.02 to 2.5 seconds at 3X the rated current is the soonest the circuit breaker ...
