What is the interrupt capacity of Telect's circuit breakers?

« Go Back


Interrupting Capacity (IC) is the maximum fault current that can be interrupted by a circuit breaker without failure of the circuit breaker. In order to select the proper circuit breaker for your application, you should know what the maximum short circuit current is, at the rated voltage, that the circuit breaker would be required to interrupt.
Carling Technologies' circuit breaker product lines offer interrupting capacities that range from 500 to 50,000 amps. The interrupting capacity (IC) for a specific circuit breaker is based on the combination of circuit configuration, current coil rating, maximum voltage rating, frequency, number of poles (or phase), if back up series fusing will be present, and the applicable regulatory agency requirements.
Telect's circuit breakers have an IC of 10,000 amps.
