According to an embodiment of the invention, a motor starter includes a connection module, which includes a second and third interface, wherein the second interface is electrically conductively connected to the third interface. The security evaluation unit can be mechanically coupled to the connection module so that an electrically conductive connection is produced between the first and second interfaces. The secure switch unit can be mechanically coupled to the connection module so that an electrically conductive connection between the third and fourth interfaces is produced, so that, in the coupled state of the security evaluation unit and the secure switch unit to the connection module; there is an electrically conductive connection between the first and fourth interfaces via the connection module, so that the control command can be transmitted from the security evaluation unit via the connection module to the secure switch unit.

Secure motor starter

An engine control device, especially an engine control device having an internal by-pass, is disclosed. The universally applicable engine control device includes an integrated by-pass function. For this purpose, a housing includes chambers that are electrically insulated from one another and that are configured both to receive a respective power subunit, and, alternatively, to receive a continuous current-bearing element.

Engine control device

An installation device includes connecting modules which, are easy to replace under aggravated conditions of access, while requiring little space. The device is provided with a retaining device for a supporting structure to be coupled thereto and additionally with a housing with integrated module slots for the connecting modules. In order to specifically assign the connecting modules to the module slots, the device is provided with one coding device for each module slot and one mating coding device for each connecting module. The device is also provided with one snap-in device on at least one of the module slots and one mating snap-in device on at least one of the connecting modules to lock and unlock the connecting modules in the corresponding module slots. One contact element each having a long side is provided for each module slot and one connecting module each is provided with one mating contact element, the contact elements being contacted with the mating contact element at an angle to its long side.

Modular installation device

Disclosed is a wiring device that can be equipped with at least one connection module and is provided with a contacting device(s). In order to protect the optionally live contacting device(s) of the wiring device with simple device(s) against accidental contact when contacting the connection module that can be coupled, an insulating device(s) is disposed at the end of and/or along the contacting device(s).

Modular wiring device

A simple and low-cost electronic function relay is specified, for example an overload relay with a bistable printed circuit board relay module. The relay includes an engagement point for mechanical operation. The relay further includes a separate reset mechanism, which can be coupled to the printed circuit board relay module, and a switching lever, which corresponds with the engagement point, for manual resetting of the printed circuit board relay module to a switched-on position.

Electronic function relay

An electric appliance is described which has a casing composed of two identically built casing shells. A spring locking hook for the snap-on mount on a mounting rail is integrated into each of the casing shells, which are assembled in mirror inversion to one another, yielding a simple, inexpensive and easy-to-assemble design composed of only a few parts.
