A heat protection device for overvoltage terminal block arrester magazines having with two-way arresters or with button arresters. According to the present invention, an S-shaped clip spring or an L-shaped clip spring is inserted in a button arrester of the 6.times.6-type or the 6.times.8-type. The clip provides one leg of the protection device having a solder preform and a switch contact to complete the circuit. In case of an overvoltage, the arc developed in the arrester causes the solder preform to melt off during an extended application of heat arising from the arrester, activating the switch contact and short-circuiting the leg of the arrester.

A heat protection device for overvoltage arrester magazines

A modular plug connector with dual terminals for multiple wire conductor pairs, such as 20 conductors in 10 double pairs. The connector has a plurality of connection modules, a plurality of slide-in units and a wire guide insert in optional arrangements. This design permits the provision of individual functions for each of a plurality of pairs of wire conductors (each double terminal) and also mixed loading of the plug-in connector. Upon occurrence of errors it is possible to indicate error status for two respective wire conductors to a central unit by means of a slide-in unit.
