Embodiment Construction

[0024] exist figure 1A plurality of protective switching devices 1 are schematically shown in . The protective switching devices 1 are arranged here in a so-called busbar complex, that is to say they are held side by side in top hat rails 7 . Such a top hat rail is used, for example, in an electrical installation switchboard (not shown) for easier installation of protective switching devices. For contacting external connecting conductors, the protective switching device 1 each has a connecting terminal 10 on its upper or lower narrow side. Shown in the region of the lower longitudinal side is a busbar 8 which has a plurality of finger-shaped pins 9 which can be plugged into the protective switches arranged side by side in the busbar complex. In the connection terminal 10 of the device 1 , it is used to connect the protective switching device 1 to the busbar 8 , for example to define a common phase. In addition to the connection to the busbar 8 , an electrical connection con...

Abstract

The terminal (10) has a clamping screw screwed into a clamping frame for clamping an electrical terminal conductor (6) introduced to the frame against a contact piece of a protection switching device (1). A screw head of the clamping screw is accommodated in an insulating sleeve. The clamping screw is movable by screwing in the clamping frame in a longitudinal direction between an open position and a clamping position. A bus bar (8) is clamped to the conductor. The sleeve and a pressure piece insulation are formed as a single piece. The sleeve is movable along a longitudinal direction of the screw.

Description

technical field [0001] The invention relates to a connection terminal for a protective switching device, in particular for a circuit breaker, a fault current circuit breaker or a circuit breaker, which has a clamping screw which can be screwed into a clamping frame, It serves to clamp an electrical connecting conductor inserted into the clamping frame against a contact piece of the protective switching device, and the invention relates to a protective switching device having such a connecting terminal. Background technique [0002] A large number of connection terminals for electrical protective switching devices, such as circuit breakers, circuit breakers or fault current circuit breakers, are known from the prior art. By means of the connecting terminal which is received and held in the housing of the protective switching device in the installed state, the electrical connecting conductor to be connected to the protective switching device can be reliably connected at one co...
