Abstract

An electrical apparatus includes a top-hat rail mount and a first conductor connection with a clamping point. A conductor can be secured via the clamping point. The electrical apparatus can be connected to a top-hat rail via a rotational movement about a rotational axis at the top-hat rail mount. In an embodiment, the first conductor connection be embodied and arranged in such a way that in the state in which the apparatus is connected to the top-hat rail via its top-hat rail mount, the longitudinal axis of a straight conductor which is accommodated in the first conductor connection is located essentially perpendicularly with respect to a straight line which is oriented orthogonally with respect to the rotational axis and which intersects the rotational axis and the clamping point.

First claim

The invention claimed is:

1. An electrical device comprising:
a top-hat rail mount; and
a first conductor connector including a clamping point, a conductor being fixable via the clamping point, the electrical device being joinable to a top-hat rail via a rotational movement about an axis of rotation at the top-hat rail mount, the first conductor connector, on a second side of the electrical device, being shaped and arranged such that, in a state where the device is joined to the top-hat rail by way of the top-hat rail mount, a longitudinal axis of the conductor accommodated in the first conductor connector is essentially perpendicular to a straight line aligned orthogonally to the axis of rotation; the straight line passes through the axis of rotation and the clamping point, the axis of rotation lying on an end of the top-hat rail facing away from the second side.

2. The electrical device of claim 1 , wherein the top-hat rail mount is arranged on a first side of the electrical device, and wherein the first conductor connector is arranged in such a way on a second side of the device, which abuts the first side of the device, that the conductor is inserted into the first conductor connector via the second side.

3. The electrical device of claim 2 , further comprising:
a further first conductor connector with a clamping point, wherein the further first conductor connector is shaped and arranged such that, in the state where the device is joined to the top-hat rail by way of its top-hat rail mount, the longitudinal axis of a second conductor accommodated in the further first conductor connector is essentially perpendicular to a straight line aligned orthogonally to the axis of rotation, and passes through the axis of rotation and the clamping point of the further first conductor connector, and wherein the second conductor is insertable into the further first conductor connector via the second side and the clamping points for the first conductor connectors are at the same distance from the axis of rotation.

4. The electrical device of claim 3 , further comprising:
a second conductor connector with a clamping point, wherein the second conductor connector is shaped and arranged such that, in the state where the device is joined to the top-hat rail by way of its top-hat rail mount, the longitudinal axis of a third conductor, accommodated in the second conductor connector, is essentially perpendicular to a straight line which is aligned orthogonally to the axis of rotation and passes through the axis of rotation and the clamping point of the second conductor connector, and wherein the third conductor is inserted into the second conductor connector via the second side and the distance from the clamping point of the second conductor connector to the axis of rotation is not the same as the distance from the clamping point of the first conductor connector to the axis of rotation.

5. The electrical device of claim 3 , wherein the electrical device is a switching device.

6. A system comprising:
a busbar including contact pins; and
the electrical device of claim 3 .

7. The electrical device of claim 2 , further comprising:
a second conductor connector with a clamping point, wherein the second conductor connector is shaped and arranged such that, in the state where the device is joined to the top-hat rail by way of its top-hat rail mount, the longitudinal axis of a third conductor, accommodated in the second conductor connector, is essentially perpendicular to a straight line which is aligned orthogonally to the axis of rotation and passes through the axis of rotation and the clamping point of the second conductor connector, and wherein the third conductor is inserted into the second conductor connector via the second side and the distance from the clamping point of the second conductor connector to the axis of rotation is not the same as the distance from the clamping point of the first conductor connector to the axis of rotation.

8. The electrical device of claim 7 , wherein the electrical device is a switching device.

9. A system comprising:
a busbar including contact pins; and
the electrical device of claim 7 .

10. The electrical device of claim 2 , wherein the electrical device is a switching device.

11. A system comprising:
a busbar including contact pins; and
the electrical device of claim 2 .

12. The electrical device of claim 1 , wherein the electrical device is a switching device.

13. A system comprising:
a busbar including contact pins; and
the electrical device of claim 1 .
