Abstract: The invention relates to a connector element for two installation breakers, adjacently attached with the broad faces thereof in contact, in particular, power breakers or residual current breakers, the housings of which are each formed from two dished housing pieces. The connector element comprises an approximately cylindrical base body with a first external diameter on the front side of which two radially-sprung, axially projecting first and second expanding arms are moulded. The external contours of the spreader arms lie on a cylindrical outer surface, the external diameter of which is smaller than the first external diameter of the base body. The free ends thereof comprise radially projecting lugs on opposed external lines, which, in the assembly state, clip behind recesses on the housings, for connection by means of the connector element, of adjacent installation breakers.

Abstract: The invention relates to a connecting element for connecting two installation units that are positioned side by side with adjacent broad sides, in particular, circuit-breakers residual-current circuit-breakers or similar, at least one of said units having a narrower module width in relation to the normal module width of an installation unit. Said element can be used for example to connect an auxiliary switch to a circuit-breaker or residual-current circuit-breaker, or an auxiliary switch to a starting-circuit breaker, or an additional auxiliary switch to starting-circuit breaker, or an additional auxiliary switch to an auxiliary switch. The connecting element comprises a base body section with two sprung arms that project in parallel. Lugs that project radially outwards and follow diametrically opposed sawtooth lines are formed on the free ends of said arms and the end of the connecting element that lies opposite said arms comprises a peripheral strip that acts as the head.

Abstract: Connecting element for connection of at least two service switching devices, e.g., circuit breakers, residual-current devices, main current switches and the like which are arranged parallel to one another and whose enclosures are formed from enclosure parts, having a sprung cylindrical base body which is in the form of a sleeve and has a circular cross section formed around a centre axis, in which case the base body which is formed with latching means can be inserted into a hole which is formed in the respective enclosure part and can be secured in an interlocking manner in the hole in the enclosure part, in which case the latching means, which can be integrally linked with a uniform material joint to the base body which is formed from a metallic material, can be formed to be autonomously sprung, so that the connecting element has a spring effect which is formed by the sprung base body and the latching means.

Abstract: An automatic switch of this type includes a switch latch for interrupting current, an overload tripping device and a short-circuit current tripping device for acting on the switch latch to trigger a current interruption. Generally there is also included at least one main contact device having at least one stationary contact and at least one movable contact, a movably supported contact lever attached to the at least one movable contact, and at least one arc quenching device associated with each main contact device. The improvement according to the invention includes a combination of an additional armature system having a magnet coil, a magnet core, a magnet armature and a striker pin.
