摘要:
An electromagnetic switching device for operationally switching currents in the load range and having an instantaneous release, connected in series, for protection against welding of the contacts (6) in the overload range is created, and has a high reliability and low overall volume. The electromagnet (2) of the switching device (1) is arranged in the middle relative to the contact bridge carrier (8) and coupled directly to the latter in the middle. The instantaneous release (3) acts via a rocker (15) on the movable contact (6) and is actuated only in the case of overcurrents, use being made of the fact that only the directly coupled drive system of the switching device is employed in the nominal current range.

A connecting system includes an electromagnetic switchgear, especially contactor, and a connector. In at least one embodiment, the system makes it easier to connect auxiliary and control lines. For this purpose, the connecting system, in at least one embodiment, includes at least one electromagnetic switchgear, especially a contactor. The switchgear includes a plurality of auxiliary contact connections and a coil connection terminal block. The coil connection terminal block is configured in such a manner that the coil connections lie in a plane with at least one auxiliary contact connection. The connecting system also includes, in at least one embodiment, a connector for simultaneously contacting the coil and auxiliary contact connections of one or more switchgears which connections lie in one plane. The connector has an internal wiring for electrically interconnecting the coil and/or auxiliary contact connections.

A switchgear unit comprising two switching devices (1, 2) which are provided with a reversing combination, which switchgear unit is of simple design and allows easy assembly and disassembly by the customer. The reversing combination comprises an assembly which is composed of a support (3) and an anchor (4) and is inserted into slots (7, 8) in connecting side walls (5, 6) of the switching devices (1, 2). The anchor (4) prevents the contact carriers (10) of the switching devices (1, 2) from being released at the same time and, when one of the switching devices (1 or 2) is switched on, prevents the contact carrier (10) of the other switching device (2 or 1) from being released.

A switchgear is disclosed with a conductor connection created via a ring cable lug. The switchgear includes a pre-mounted structural component provided with a holder and a screw with a washer assembly which is held by the holder and forms, together with a connection part, a clamping point for a conductor connection created by means of a ring shoe lug. The holder can be displaced between an open position and a closed position of the clamping point, and is subjected to the action of a spring element that holds it in the open position when the clamping point is released.

A switching device with a four-legged coil and specially designed plug-in locations on the device housing. The first type of plug-in location is connected to the first winding end and will only accept a first type shape-coded connecting terminal. The second type of plug-in location is connected to the second winding end and will only accept a second type shape-coded connecting terminal. This reliably prevents accidental short-circuits.

A contact arrangement for switchgear with multiple disconnects by contact points connected in parallel of two contact bridges aligned in a contact actuation link uses a spring collar for a contact pressure spring. The spring collar has cutouts transverse to the spring-action direction into which the contact bridges with the spring collars can be inserted and locked in place transverse to their longitudinal direction. The spring collar is rounded at two facing sliding surfaces in the contact actuation link aligned transverse to the longitudinal direction of the contact bridges. This assures optimal fitting of the contact bridges to the fixed contact components without jamming the spring collar in the alignment.

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.
