Purpose

SZD11 series load break switch is mainly applicable to the electric circuits of AC 50Hz, rated operating voltage 380V and below, rated current up to 100A, or can directly control small capacity AD motor. With good functional characteristics and small structural dimension, SZD11 series applies to ventilating device, air-conditioning and water pump system, main switch of industrial equipment, and is used for insulation and safe isolation. (equivalent to foreign KG20~KG100 load break switch)
