This document applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V AC or 1 500 V DC.
It covers control and protective switching device (CPS):
– which provides protective and control functions for circuits and motors;
– where its control function is operated exclusively otherwise than by hand;
– which provides continuity of service after over-current conditions; and
– which can have additional functions, such as isolation or communication.
