Circuit breaker

An installation switching device includes an insulating housing having a front face, and a switching handle disposed on the front face and configured to be operated by an operator and switched between a switched-on position and a switched-off position. The installation switching device also includes a slide fitted to the front face and moveable between a locked position and a released position. The slide is in the form of a frame and having at least one transverse web transverse to a movement direction of the slide and a holding projection configured to block any switching of the switching handle when the slide is in the locked position and to release the switching handle for switching when the slide is in the released position. The front face includes at least one structural element corresponding to the at least one transverse web. The installation switching device also includes a lead-sealing device configured to prevent movement of the slide from the locked position, wherein the at least one transverse web and the at least one structural element support the lead-sealing device.

The disclosure relates to a service switching device with an insulating housing and a connection terminal arrangement for the terminal connection of a connecting conductor with an annular terminal lug on a connecting plate mounted in the device interior, with a clamping screw, which has a screw head and a screw shaft, the screw shaft passing through the annular terminal lug and being in threaded engagement with a thread element during the terminal connection of the connecting conductor. A terminal accommodating area has an insertion opening for the connecting conductor and an access opening for the screw head for actuation thereof. The connecting plate has a holding section for locking the thread element.

Service switching device with a connection terminal arrangement

An installation switching device includes a housing having a terminal connecting area and a screwless spring-loaded terminal fixed in position in the terminal connecting area, and a spring operating lever. The screwless spring-loaded terminal includes a clamping spring having a contact limb, a clamping limb having a clamping window with a clamping edge, and a curved spring rear connecting the contact and clamping limbs and configured to interact with a mount part surrounding a clamping strip, such that a connecting conductor is clampable between a rear face of the clamping strip and the clamping edge.

Installation switchgear having a spring-loaded terminal arrangement

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.
