A connection module arrangeable on a connection side of a main casing of a power switch comprises a plurality of connection spaces limited by a removable covering cap and by lateral separation walls. When the connection module is mounted, connection bars provided with a through hole and arranged in the main casing are projected into the connection spaces, which are provided with lateral guiding elements formed in the separation walls for frame terminals surrounding the connection bars and for guiding elements on bottom side for screw plates placed under the connection bars. A cylindrical reception area coaxially extends with respect to the associated through hole from each connection space bottom and is closed on a bottom side by a breakable wall part and receives a connection sleeve through the broken wall part in such a way that the connection sleeve is at least indirectly connected to the associated connection bar.

Connection module for a power switch

An electrical switching device such as a low voltage power circuit breaker, can have a cover with a slot-like opening for providing access to a switch lever of the switching device. The cover can extend to cover over any chambers for shunt releases and/or auxiliary switches etc. which chambers can be located on both sides of the switch lever within the enclosure. The cover can also have fastening devices for attachment of a mechanical rotary actuator or a motor drive. The cover is connected to the enclosure in a manner which provides for a simple opening and closing of the cover, and essentially eliminates the danger of losing and mixing up such covers. The cover is designed with bearing legs which are bent at an angle of 90 degrees in relation to the cover plane. The bearing legs are preferably parallel to one another and laterally overlap the enclosure. The cover is mounted to the enclosure by means of the bearing legs and pivot bearing with coaxially interlocking pivots and pivot bearing openings.
