A wiring structure includes: multiple wiring modules configured to be installed on a rail that extends in a predetermined first direction, so as to be adjacent to one another along the rail by being placed on the rail from the side of a second direction orthogonal to the first direction; an IO unit configured to be attached to the plurality of wiring modules from the second direction side to thereby be electrically connected to the multiple wiring modules. In each of the multiple wiring modules, a lead wire extending in a third direction that intersects the first direction and the second direction, from a first face of the wiring module that lies on the third direction side, is connected to the wiring module.

An electrical contactor assembly includes an electrical contactor, a post in electrical communication with the electrical contactor, an insulator body, and a heat sink. The insulator body is in intimate mechanical contact with the post. The heat sink is in intimate mechanical contact with the insulator body and is in thermal communication with the electrical contactor through the post and the insulator body such that heat flowing between contactor and the heat sink flows through the post and the insulator body.

A support rail on which a plurality of housings, which can be strung together and which are equipped with electrical contact elements and/or functional elements, can be arranged is mounted onto a mounting base in a mounting position, even in a state in which the housings have already been strung onto the support rail prior to the support rail being mounted. The support rail is retained by two or more latching devices which are placed in position on the mounting base prior to the support rail being mounted. The latching devices and the support rail are configured such that the support rail can be placed onto the latching device and locked onto it without using any tools. The latching device has a base section has a cross-section relative to the mounting position on the mounting base which corresponds to a U rotated by 180°, The base section is divided into a horizontal base bar and two side bars perpendicular thereto and the latching element is supported on the mounting base as a thrust bearing via the two side bars.

A mounting rail is provided that includes a DIN rail and one or more heating cable channels. A channel defined by the DIN rail may include one of the heating cable channels. Heating cables may be installed in the heating cable channels using adhesive and/or heat transfer material to form an electronics heating module. The heating cables may be self-regulating heating cables. The mounting rail may include multiple heat transfer fins that transfer heat generated by the heating cables to environment surrounding the mounting rail. A terminal block may be mounted on the DIN rail and may supply electric power to the heating cables.

A converter comprises a housing having a mounting structure for mounting the converter to a DIN rail. A converter circuit is disposed within the housing and comprises one or several wide-bandgap semiconductor based active switching element(s). The converter circuit is adapted to perform a total harmonic voltage distortion measurement and to perform a control function based thereon.
