AC Contactors; (HS: 8505 ); (ICS: 27.010)

National Standard of the P.R.C., Minimum Allowable Values Of Energy Efficiency And Energy Efficiency Grades For AC Contactors (5 page(s), in Chinese)

This document specifies the energy efficiency grade, energy efficiency limit value, energy efficiency evaluation value, test methods of AC contactor.

This document is applicable to three pole Electromechanical, direct acting and integral contactors of AC-3 with rated frequency of 50Hz, rated working voltage of main circuit of 1000V and below, rated working current of 6A ~ 630A and  rated control power supply voltage of AC 400V and below.

This document does not apply to external power saving devices, household and similar contactors and semiconductor contactors (solid state contactors).

Note: the "direct acting" mentioned in this document refers to the products in which both the contact system and the electromagnetic system are direct acting.
