Abstract

Device to automatically or manually test the efficiency of the most sensitive and main components of an electrical apparatus for proctecting, controlling or signalling, in particular of a residual current circuit breaker, without interrupting the electrical supply, wherein the mechanical disconnecting chain which starts from the detector of the failure (relay) (10) to the hooking (17) of the mechanism is switched off for a litte while, decoupling the lever which usually transmits the motion in two half-lever (20) and (21) hinged on the same axis (14), when the interruption of the click mechanism is wished, having two possible mutual positions, the first one corresponding to the normal working order, the second one with the two half-levers (20, 21) free. <IMAGE>
