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 a.c. or 1 500 V d.c. CPS are intended to provide both protective and control functions for remotely controlled circuits. They may also fulfil additional functions, such as isolation.
