Definitions

• the invention relates to a current switch according to the preamble of claim 1.
• a gattungsge speciallyer power switch is for example an additional ⁇ switch for mounting on a circuit breaker, which is known from DE 39 20 822 C2.
• This conventional additional switch has a switching mechanism which can be actuated both by the circuit breaker via a coupling element and by an actuating hand toggle articulated on the additional switch.
• the switching mechanism switches an auxiliary and / or error signal contact.
• the manual control toggle shows the switch position of the additional switch to the outside.
• Such conventional additional switches are usually attached to the side of the circuit breaker and coupled to it, for example by brackets.
• the additional switch is held with its housing on the circuit breaker, which is snapped onto a top-hat rail, which is usually fastened horizontally to a wall.
• the installation position of the additional switch is determined so that the manual control knob in the upper end position indicates that the additional switch is switched on. This corresponds to the uniform regulations in all countries of the European Union.
• the invention is therefore based on the object of developing the power switch according to the preamble of claim 1 in such a way that it can be used universally at the lowest possible cost.
• the current switch according to the invention consists of two separate modules which can optionally be assembled in different positions. In this way, a uniform power switch kit is created for all countries, so that the storage costs are reduced and the administrative effort is reduced.
• the two modules are assembled on site in a manner that complies with the regulations and installed as a power switch.
• the current switch divided according to the kit can be both an externally tripped additional switch for mounting on a circuit breaker and the self-tripping circuit breaker itself.
• the current switch is expedient to design as an additional switch which can be triggered externally and which can be attached to a circuit breaker via coupling devices.
• the add-on module of the kit which is assembled with the basic support module, carries not only the manual control knob but also the complete switching mechanism. This results in a division of the current switch into a basic support module which only has the electrical contact and an add-on module which has all the mechanical components. This division into an electrical module and a mechanical module also has a great advantage in maintenance. In the event of a mechanical defect, only the mechanical module has to be replaced so that the running operating costs can be reduced.
• a mechanical module of an additional switch mounted adjacent can be implemented for test purposes, so that the test work can be carried out without having to loosen the connections.

• the add-on module is first inserted into the recess in the base support module so that the position of the manual control knob corresponds to the regulations for the switched-on position of the power switch.
• the assembled kit is then attached to the circuit breaker in the correct position depending on the position of the busbar. If the current switch is used as an additional switch, the assembled kit is installed with the line circuit breaker using the coupling devices. This assembly is particularly advantageous for the fitter because there can be no accidental confusion of the installation positions.
• the base support module of the additional switch is provided on only one half in the vertical direction with connections accessible from the front.
• the basic support module can then be attached to the snapped circuit breakers must be mounted so that this half lies on the side facing away from the busbar, so that short circuits are avoided due to accidental contact of the cables inserted in the connections of the additional switch with the busbar.
• the interaction of the impact ice with the contact in the base support module is thus reliably ensured, in particular if both modules have the same width and the different installation positions of the add-on module are offset by 180 degrees to one another in the base support module.
