Abstract
(EN)
The present invention includes: a virtual short-circuit signal driving circuit unit connected to both ends of a test button in a short circuit breaker; a virtual short-circuit signal recognition circuit unit which recognizes a short-circuit detection signal and outputs a diagnosis signal; and a virtual short-circuit signal breaking circuit unit which guides the short-circuit detection signal to earth so that the short-circuit detection signal does not flow to the driving unit.
