Abstract
Proposed is an automatically testable short circuit breaker that includes: a pseudo short circuit signal driving circuit unit connected to opposite ends of a test button in a short circuit breaker; a pseudo short circuit signal recognition circuit unit which recognizes a short circuit detection signal and outputs a diagnosis signal; and a pseudo short circuit signal shut-off circuit unit which induces the short circuit detection signal to grounding so that the short circuit detection signal does not flow into the driving unit.
