Abstract: A fastening device for fastening a DIN rail to a wall includes: at least one fastening element having a wall fastening portion for fastening the fastening element to the wall, and a DIN rail fastening portion for fastening the fastening element to the DIN rail. When in a fastened state, the DIN rail fastening portion is guided at least in some regions through an opening formed in the DIN rail. The DIN rail fastening portion includes a tongue and groove system into which a portion of the DIN rail is inserted in the fastened state.

Abstract: An electrical terminal block with simplified switching operations, which can be produced in a cost-effective and time-saving manner.

Abstract: Modular terminal block, in particular a multi-level terminal block, for clamping a plurality of jumper wires that can be led thereto in an orderly fashion using a comb-type structure. The comb-type structure can be put together from separate bars that have clip-on-portions and cooperate with mating clip-on portions on the terminal block such that the bars can be removed from the terminal block when no comb-type structure is needed.

Abstract: An electric terminal block having a block housing, two conductor connection elements, two current bars, and two additional current bar pieces. Each current bar has a connection portion, and first and second contact portions, each connection portion being paired with a conductor connection element. To obtain a reliable switching sequence when plugging and unplugging an operating or test plug, the terminal housing is equipped with two spring elements, each of which has a connection portion and an elastic contact portion; each of the spring elements is electrically connected to one of the current bar pieces; the contact portions together form a second contact region for receiving the plug, and being mutually spaced when the plug is not plugged in. The contact region of the spring elements is arranged in front of the contact region of the current bars in the plug-in direction of the plug.

Abstract: A terminal block has an insulator housing, at least two busbars and at least four connection elements, there being at least two connection levels in the insulator housing arranged one over the other. Each connection level has a busbar receptacle chamber for receiving a busbar and two mutually opposite conductor connection chambers on ends of chamber for receiving a respective connection element, the chambers being open on an insulator housing first side for busbar assembly in the chambers and wherein the conductor connection chambers are open on a second side of the insulator housing for assembly of the connection elements in the conductor connection chambers. The insulator housing first side is designed at a right angle to the insulator housing second side to give an busbar assembly insertion direction into a chamber at a right angle to a connection element assembly insertion direction into a conductor connection chamber.
