A modular distributing rack with protection modules, which as a result of the disconnection of the circuit can be tested.

摘要

A distribution frame module (20) comprising a generally rectangular module block (54) having a front face with two parallel opposing rows of wire connectors (46) and a row of protector apertures (40) between the connector rows for accepting overload protector elements (32). Each wire connector has a spring contact finger (50) extending into one of the protector apertures, and each protector element has at least two external contacts (120, 126) and a conductor (132) therebetween to make an electrical connection between opposing spring contact fingers when inserted into a protector aperture. In the absence of a protector element therein, opposing spring contact fingers are in contact for electrical connection with each other.
