An arrangement for electrically connecting a circuit breaker to a laminated busbar in a switch gear cabinet in which the circuit breaker has at least one terminal to be contacted by a connecting bar and in which the laminated busbar includes at least one conducting layer for conducting electric current which is covered by adjoining insulating layers attached thereto, the arrangement including: a first cylindrical connecting element and a second cylindrical connecting element which are arranged at a distance to each other at the conducting layer and project away from the conducting layer; an electrically conducting distribution bar which is mounted to free end portions of the first and second cylindrical connecting elements; and a terminal member which is mounted to the distribution bar at a center between the first and second cylindrical connecting elements. The terminal member is to be contacted by the connecting bar.

Arrangement for connecting a circuit breaker to a conducting layer of a laminated busbar and switchgear comprising such an arrangement

A coupling element for electrically coupling a lateral connecting portion of a first laminated busbar to a lateral connecting portion of a second laminated busbar, the coupling element having a base body that includes a sandwich of conducting layers of sheet metal and intermediate insulating layers arranged in between the conducting layers for electrically insulating the conducting layers from each other. Each of the conducting layers includes a first layer section that is associated to the lateral connecting portion of the first busbar and a second layer section that is associated to the connecting portion of the second busbar. The first and second layer sections are electrically insulated from each other by an insulating element and each of the first layer sections includes a first circuit breaker connecting terminal that is adapted to be electrically connected to an input terminal of a circuit breaker.

Laminated busbars and direct connection of air circuit breakers in bus coupler sections

A laminated busbar includes: a base body comprising conducting layers and insulating material to electrically insulate the conducting layers from each other. The conducting layers and the insulating material are clamped together by mechanical means and/or a profile is connected to the base body. In an embodiment, no glue or adhesive is arranged between at least one conducting layer and at least one insulating material.

Laminated busbar and arrangement comprising laminated busbars

A switch gear module for installation in a switch gear cabinet includes: a switch gear module housing, the housing including power circuits and first electrical power devices including breakers, contactors, and motor circuit breakers for supplying electric power to an electric load including an electric motor, and electric control circuits and auxiliary circuits controlling the first electrical power devices. The power circuits and the first electrical power devices are contained in a first power-unit housing forming a first functional power-unit and the electric control circuits and auxiliary circuits are contained in a separate second control- and auxiliary circuit housing forming a second functional control- and auxiliary circuit unit. Each of the first functional power-unit and the second functional control and auxiliary circuit unit includes an interface for connecting the power circuits and electrical power devices contained in the first power-unit housing.

Switchgear module for installation in a switchgear cabinet and switchgear cabinet including such a switchgear module

An arrangement includes: a module insertable into a housing or removable from a housing; and a slide-in compartment for receiving the module. The module is reversibly removable from the slide-in compartment. At least one side wall and/or a compartment rear wall and/or a compartment base of the slide-in compartment in an inserted state of the module forms or form a side wall and/or rear wall and/or a base wall and/or a roof of at least one module.

Arrangement comprising a compartment and a slide-in module

The invention relates to an electrical low-voltage switchgear, comprising at least two power units accommodated in slide-in units or in a housing, and comprising control units assigned to the power units. The control units are spatially separated from the power units and power levers and are connected to one another via signal lines.

Electrical low-voltage switchgear assembly

The invention relates to a modular rear wall for a switching system module, in particular an insertion module. Said modular rear wall comprises a measuring device which is integrated therein and which forms an integral component of the switching system module. The invention also relates to a switching circuit module which comprises said type of modular rear wall, in addition to a switching system comprising at least one switching system module having a modular rear wall.

Module rear wall for a switchgear assembly module, switchgear assembly module and electrical switchgear assembly

The invention relates to a module front for a switchgear module, particularly a slide-in module, comprising a control device, the control device being integrated in the module front, and the module front forms an integral component of the switchgear module. The invention relates to a switchgear module, particularly a slide-in module provided with an inventive module front, and to a switchgear equipped with at least one switchgear module of this type.

Module front for a switchgear assembly module, switchgear assembly module and electrical switchgear assembly

The invention relates to an electric switching system which comprises a housing and components which are arranged therein and which are embodied as a control and/or measuring unit. Said components are arranged in modular-type drawers. At least one base module comprises at least one module support profile, in addition to lateral walls and front-sided insertion elements. One front wall of the base module, preferably the front side thereof, is formed by a control unit and the opposite front wall thereof of the measuring unit, and the dimensions of the control and measuring unit are adapted to the size of the module.
