In one embodiment of the present invention, a production method for an electromagnetic switching device includes the following steps in the sequence listed: producing a one-piece switching chamber, producing a contact bridge carrier and equipping the contact bridge carrier with movable contact bridges, wherein the contact bridges include a plurality of primary contact bridges and at least one auxiliary contact bridge; inserting the contact bridge carrier equipped with the movable contact bridges into the switching chamber; inserting partition elements into the switching chamber so that each partition element is arranged between a bridge contact point of one of the primary contact bridges and a bridge contact point of one of the auxiliary contact bridges, and equipping the switching chamber with fixed primary counter-contact points; fixing primary covers to the switching chamber so that the primary covers cover the primary counter-contact points and fix the partition elements in the switching chamber.

An electromagnetic switching device for controlling a branch includes, in at least one embodiment, a housing with a length in a longitudinal direction, with a first end side, which is oriented at right angles with respect to the longitudinal direction, and with a second end side, which is opposite the first end side and is oriented at right angles with respect to the longitudinal direction; a control coil, which is arranged in the housing, for actuating an electrical switch with a first and second coil contact; and a first and second connection element, which are arranged partially in the housing. In at least one embodiment, the connection elements are capable of being displaced in the longitudinal direction relative to the housing between a first and a second end position in such a way that they are freely accessible on one of the end sides in the first end position, are freely accessible on the other of the end sides in a second end position, and are electrically connected to the associated coil contacts both in the first end position and in the second end position.

A switching system includes switchgear that can be contacted via pin contacts. In at least one embodiment, the switching system is provided with pin contacts and mating pin contacts and at least one device(s) for the transmission of force onto the switchgear, thereby allowing to establish and interrupt contact to the switchgear even when only little space is available.

According to the invention, the busbar system comprises at least one first () and one second busbar block () with busbars (), whereby the busbars () of the first busbar block () are electrically connected to a number of supply terminals () mounted in a fixed manner thereon and to the busbars () of the second busbar block () by means of a multiphase connecting plug ().

The aim of the invention is to protect an electromagnet switching device when a load is switched to a supply voltage. A current that flows through the load contact is monitored. The electric circuit is interrupted when the current exceeds a threshold value that is below the current carrying capacity of the load contact. The electric circuit is automatically closed again after the current which flows through the load contact has decreased.
