Abstract
Disclosed is a plug-in base for compact low-voltage protective circuit breakers. The plug-in base comprises a mounting plate and two identical plug-in units disposed thereon at opposite ends thereof. Jumper-like contact laminations are disposed in the plug-in units extending parallel to the current path in a mounted protective circuit breaker. The mounting plate has disposed in the area between the plug-in units a cut-out and a strip extending adjacent thereto which are freely accessible. A padlock may be secured through the cut-out to the strip to prevent mounting of a circuit breaker. The mounting plate is further provided with an extension projecting laterally therefrom which cooperates with a safety tripping pin of a circuit breaker. To lengthen the leakage path and to shield the contacts, the plug-in units have projections and ribs which are placed in front of the contact surfaces of the contact laminations facing a mounted circuit breaker.
