Scope and objectThis part of IEC 60947 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.CPSs are intended to provide both protective and control functions for circuits and are operated otherwise than by hand. They may also fulfill additional functions@ such as isolation.The object of this part is to state:?C the characteristics of CPSapos;s;?C the conditions with which CPSapos;s shall comply with reference to their operation and behaviour@ their dielectric properties@ the degree of protection provided by their enclosure where applicable;?C the tests intended to verify that these conditions have been met@ and the methods to be adopted for these tests;?C the information to be marked on or given with the CPSapos;s.
