QJX2 series of star-delta starter,is applicable for circuit of AC50Hz or 60Hz, voltage up to 660V,current up to 95A,as motor heavy-load starter,it has timer and can starting "star-delta" transfer automatically to reduce the motor starting voltage and current.QJX2 series starter is applied to control motor which has "delta"
connetion.when motor starts star-delta transfering,"star" start current
is about 1.8-2.6 times of motor rated current,but "delta" connection
is about 0.58 times if rate current.
QJX2 seris production technical data,see Table1
