Abstract

The present invention relates to a thermomagnetic circuit-breaker comprising a moulded case containing a movable contact and a fixed contact, the movable contact being connected to an operating lever controlled by a trip lever and operatively associated to an operating knob, characterised by the fact that it comprises an auxiliary lever engageable with said movable contact to hold it at a predetermined distance from said fixed contact during closing operations, said auxiliary lever being operatively coupled with the operating knob to release the movable contact allowing completion of the closing operation. <IMAGE>
