Abstract

The low-voltage power circuit breaker which has ON, OFF and TRIP positions is able to separate the contact pieces (1, 2) very quickly after tripping in response to an excess current. The excess current trip device in this case acts directly on a transmission lever (10) which on the one hand unlatches a switching-off latch (8) and on the other hand releases the support from two pivoting discs (14) which are spring-loaded in the switching-off direction. Thereafter, two mutually separated mechanical systems are accelerated. The first system, consisting only of the transmission lever (10), of the switching-off latch (8), of a switching-off lever (5) with an energy-storing switching-off spring (6) and of the moving contact piece (2) carries out the contact separation very quickly. The second system, which is now separated from the first system and contains all the other parts of the mechanical drive, is moved by the pivoting discs (14) which are spring-loaded in the switching-off direction. When the power circuit breaker is switched on and off by hand, the two systems are coupled to one another. Switching on by hand takes place independently of the operator's speed of operation, by releasing a switching-on latch (34) of the spring-loaded moving contact piece (2). <IMAGE>
