Embodiment Construction

[0022] figure 1 and 3 Shown is a switching lever 1 for manually closing and / or opening the switching contacts of a switching device and a triggering device for automatically opening the switching contacts, wherein the switching lever 1 has an operating flange 2, wherein the operating flange 2 A separate handle part 3 is arranged on it.

[0023] The switching device according to the invention may be any type of switching device. The switching device is preferably designed for circuit protection measures, in particular line protection switches and / or fault current protection switches.

[0024] Through the measures according to the invention, the actuating flange 2 can be adapted, for example, to the loads caused by the switching device and the service life of the switching lever 1 and thus the entire switching device can be extended. Thus, when using a housing that has to be pushed over the switching lever 1 in order to assemble the switching device, it can be achieved that t...

Abstract

The invention relates to a switchgear, especially an automatic cut-out and / or a fault-current circuit breaker, said switchgear comprising a switch lever (1) for manually closing and / or opening switch contacts, and a release device for automatically separating the switch contacts, the switch lever (1) comprising an actuating extension (2). According to the invention, in order to prolong the service life of the switchgear, especially of the switch lever, a separate handle part (3) is arranged on the actuating extension (2).

Description

technical field [0001] The invention relates to a switching device, in particular a circuit breaker and / or a fault current breaker, with a switching lever for manually closing and / or opening the switching contacts and a triggering device for automatically opening the switching contacts, wherein , the switch lever has an operating flange. Background technique [0002] Switching devices are known which have a switching lever for manually closing and / or opening the switching contacts. Such switch levers are subjected to various loads during operation. In addition to manual operation, the switching lever must also withstand the load caused by the automatic switching device. Due to the force exerted by the switching device on the switching lever, the switching lever may be damaged or broken. As a result, an otherwise perfectly normal switching device cannot function. Contents of the invention [0003] It is therefore the object of the present invention to provide a switchin...
