Definitions
- the invention relates to a residual current circuit breaker according to the preamble of the claim 1.
- Residual current circuit breakers have a transformer system as internal components a summation current transformer, primary windings and a secondary winding, wherein the primary windings through phase conductors plus drawn through the converter Neutral conductors are formed.
- phase conductors and the neutral conductors are in the known residual current circuit breakers connected at opposite ends to terminals, which in general are designed as screw terminals.
- the plug contact can rise from the ground protrude that the surface of the plug contact parallel to the narrow side surfaces of the residual current circuit breaker.
- a suitable angled form the plug contacts so that their plane parallel to the broad sides of the residual current circuit breaker.
- Fig. 1 shows a residual current circuit breaker 10, the lower housing part 11 and has an upper housing part 12, the lower housing part approximately in its center in Bottom region has a recess 13 on which a fixed nose 14 and a movable nose 15 are arranged with which the residual current circuit breaker is snapped onto a top-hat rail 16, which is shown schematically on a Power distribution rail assembly 17 is attached.
- the two plug contacts 26 and 28 lie in a plane which is parallel to the longitudinal extent the Hulprofilschiene 16 extends and engage in corresponding openings 30 into the busbar distribution 17.
