Circuit breaker

An installation switching device includes a housing, a main contact point having an arc quenching chamber, an input terminal, an output terminal, an impact-style armature system configured to move the main contact point to an open position, a latching mechanism having a latching point and configured to open an isolating contact point disposed in a secondary current path parallel to a main current path, a main thermostatic bimetallic strip configured to act on the latching point to as to cause the main contact point to remain in the open position, a current limiting resistor disposed in the secondary current path, a selective thermostatic bimetallic strip disposed in the secondary current path and configured to act on the latching mechanism, a handle configured to act on the latching mechanism so as to open and close the main contact point, and a phase connecting rail.

Installation switchgear

An installation switching device comprises a housing having a front and a rear face, a mounting side, at least one front and rear narrow side, two wide sides and having an opening at least on the rear face. The installation switching device further comprises a screwless terminal connection including a clamping spring disposed in a terminal connection space and configured to connect a plurality of connecting conductors and a terminal cover part swivelably connected to the housing and configured to cover the opening, the terminal cover part having a terminal face with a plurality of terminal openings, each corresponding to one of the plurality of connecting conductors to be connected and a guide device molded onto each of the at least one terminal openings and configured to guide the connecting conductors.

Installation switching device

The invention relates to an installation switching device comprising a housing, with a front and rear face, a mounting side, front and rear narrow sides and wide sides, and with two screwless terminal connections with in each case at least one clamping spring for the connection of connecting conductors which are fixed in position in a terminal connection space of the housing. The terminal connection space is open towards the housing wide sides and towards the face. Each terminal connection is covered by an associated terminal cover part connected pivotably to the housing, which has a terminal face with a number of terminal openings corresponding to the number of connecting conductors to be connected, and guide means moulded onto each terminal opening for the connecting conductors, which also has two side areas which cover the terminal connection laterally in the direction of the wide sides. Spring actuating means are moulded onto the cover part and are constructed in such a manner that, when the cover part is swivelled against the clamping spring they load the latter so as to open it.

Clamping connection for connecting a conductor to an installation switching device, comprising a clamping spring, acting on the conductor end as compression spring, for clamping tight the conductor end at an abutment, wherein
