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 electrical control box, particularly for low-voltage systems, includes an interior defining a compartment. At least one stationary counterpart contact and a counterpart element are disposed in the compartment. At least one drawer preferably being elongated rectangularly in the vertical direction is to be inserted into the compartment for holding electrical and/or electronic components for switching, controlling and the like. The at least one drawer has a back to be located in the interior and a bottom. Rollers are disposed on the bottom. At least one contact location is disposed on the back for respectively contacting the at least one stationary counterpart contact. A suspension joint disposed on the bottom is to be suspended at the counterpart element when installed, for permitting the at least one drawer to be swiveled between a first suspension position in which the at least one drawer is hinged obliquely forward and a second insertion position after the suspension position and to be moved between the second insertion position and an inserted position, and back again.
