ABSTRACT:
A power interrupter for non-destructively protecting for instance 120 Vac equipment test when that equipment is likely (i.e., expected or designed) to develop a short circuit across the ac power line. The speed of response (50-microsecond turn-off) is significantly faster than that of ordinary line circuit breakers or fuses, both of which react in milliseconds. The device can be applied to any circuit protection problem where speed of response is crucial.
