Embodiment Construction

[0027] figure 1 A fused switch assembly is shown, which has three fused switch units 10, each fused switch unit 10 having a fixing and contacting device 11 for a busbar 90, and a fused switch unit for switching on and off all fused switch units. 10 circuit switchgear, and a safety plug 25 with a safety element 20 is respectively housed in each switch safety unit.

[0028] Each fused switch unit 10 is fastened to a busbar by means of a circumferential spring 95 .

[0029] The switch and locking device of the present invention are in figure 1 In the shown embodiment, a switching lever 40, a spring-loaded switching rod 50, an actuating device 60 with a pressure lever 61 for each fused switch unit 10, a spring-loaded locking device 70 and a Also spring-loaded braking device 80 . The spring 52 of the switching rod 50 has a significantly greater spring rate than the spring 62 of the actuating device and the spring 81 of the brake device, whereas the spring rates of the springs 62...

Abstract

The invention relates to a multipolar circuit-protection assembly for a collector rail system, comprising at least two circuit-protection units (10) for receiving a respective fuse (20). Said circuit-protection units (10) comprise a fastening- and contact device (11) for a collector rail. The inventive multipolar circuit-protection assembly comprises a switching device for closing and interrupting the electrical circuit of all the circuit-protection units. Said multipolar circuit-protection assembly also comprises a combined switching and blocking device (30) composed of a switching lever (40), an actuating device (60), a blocking device (70) for each circuit-protection unit (10) and a stopping device (80).

Description

technical field [0001] The invention relates to a multi-pole switch safety assembly of a bus bar system, which has at least two switch safety units each containing a safety element, wherein the switch safety unit has a bus bar fixing and contact device, and has a Switching device for making and breaking the circuits of all switching fuse units. Background technique [0002] The above-mentioned fuse switch assembly is especially used for insurance of three-phase AC circuits that require a three-pole switch fuse assembly. [0003] Since such fused switch assemblies are also used by laymen, it is often a problem that incorrect use of the fused switch assembly leads to damage to the device. [0004] A safety switch is known from DE4207156C2. [0005] From DE4207156C2 a structure of an electrical switch and a safety switch is known, in which a safety element can be inserted. The contacts of the safety switch are connected or disconnected via movable contacts to a fixed counter...
