ABSTRACT:
A puffer breaker employs a low energy actuating mechanism during normal opening and closing operation and a pyrolytic cartridge actuating mechanism for high speed operation under fault conditions. A current detector is provided in circuit with the puffer breaker to control operation of the actuating mechanisms, so that whenever a fault condition is detected, the pyrolytic cartridge actuating mechanism rapidly opens the circuit breaker.
