43 Type Electronic Voltage Relay protection ( Motor Control Relay ) advange as follows:
1,Cycling display of three phase(single phase) voltage
2,It's a comprehensive digital voltage protector equiped with a MCU (microcontroller)
3,Multiple protection function such as overvoltage,undervoltage,open phase,reverse,three phase unbalance protection
4,Seperate setting of overvoltage,undervoltage,overvoltage delay time and undervoltage delay time
5,Manual reset and automatic reset are optional,and the automatic reset time can be set to be 1s or 5s
6,Functional setting by dial switch
7,Three phase voltage unbalance (phase voltage difference above 5%)protection,with delay time of 3s
8,Fail safe
9,Digital display of fault reason and fault voltage,facilitating fault handling
