Abstract

An electrical switching device including an electric power switching module including a block of three input terminals and three output terminals, each input or output terminal being connected to a stationary contact of an electrical switch also including a mobile contact, configured to switch between an open position and a closed position, the mobile contact configured to be moved by an electromagnetic drive mechanism, and a control module, including at least one control input terminal and at least one control output terminal. The control module includes the electromagnetic drive mechanism configured to be supplied by the control terminals to control a position of one of the mobile contacts. A supervision module includes an auxiliary input contact terminal and two auxiliary output contact terminals, the auxiliary input contact terminal being shared by the two auxiliary output contact terminals, the power module being removable separately from the control and supervision modules.

First claim

The invention claimed is:

1. An electrical switching device comprising:
an electrical power switching module, comprising a terminal block of three input terminals and three output terminals, each input or output terminal being connected to a fixed contact of an electrical switch, which also comprises a movable contact configured to switch between an open position and a closed position according to a positioning of the movable contact relative to the fixed contact, the movable contact configured to be moved by an electromagnetic drive device;
a control module comprising a set of control terminals including at least one control input terminal and at least one control output terminal, the control module comprising the electromagnetic drive device which can be supplied by the control terminals to control a position of one of the movable contacts;
a monitoring module comprising an auxiliary input contact terminal and two auxiliary output contact terminals, the auxiliary input contact terminal being common to the two auxiliary output contact terminals; and
the power module being detachable separately from the control module and monitoring module.

2. The switching device as claimed in claim 1 , wherein the set of control terminals and a set of monitoring terminals including the auxiliary input and output contact terminals are mounted on either side of the terminal block of the electrical power switching module.

3. The switching device as claimed in claim 2 , placed in a casing and wherein the set of control terminals, the set of monitoring terminals, and the block of terminals of the electrical power switching module are mounted on a front face of the casing.

4. The switching device as claimed in claim 3 , wherein each of the set of control terminals, set of monitoring terminals, and terminal block of the electrical power switching module is protected by a protective cover having a visual distinguishing sign.

5. The switching device as claimed in claim 1 , wherein the electromagnetic drive device comprises two electromagnetic coils, and the control module comprises a common input control terminal configured to supply the electromagnetic coils.

6. The switching device as claimed in claim 5 , comprising two electrical coupling elements configured to form, respectively, a fixed input control contact of a first electromagnetic coil and a fixed input control contact of a second electromagnetic coil, and comprising a connecting element comprising two connection apertures, configured to interact with the electrical coupling elements, and to form a common input contact terminal for supplying power to the first and second electromagnetic coils.

7. The switching device as claimed in claim 1 , wherein the monitoring module comprises two switches, each switch configured to switch between an open position and a closed position, each switch comprising a fixed input contact connected to the common auxiliary input contact terminal, and a fixed output contact connected to one of the auxiliary output contact terminals, the fixed input contact and a fixed output contact configured to be electrically connected by a movable contact held by a movable contact blade, the movable contact blade being fixed in a support element which is configured to be moved by an electromagnetic drive device.
