BS EN 60947-6-2-2003低壓開關(guān)設(shè)備和控制設(shè)備.多功能設(shè)備.控制和保護(hù)開關(guān)裝置(或設(shè)備)(CPS)

This 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.\nCPSs 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.\nThe object of this part is to state:\n- the characteristics of CPS's;\n- the conditions with which CPS's shall comply with reference to their operation and behaviour, their dielectric properties, the degree of protection provided by their enclosure where applicable;\n- the tests intended to verify that these conditions have been met, and the methods to be adopted for these tests;\n- the information to be marked on or given with the CPS's.
