Features & details
Multi-functional and intelligent protection device. A 3-phase relay protector that is equipped with many intelligent protections i.e overvoltage, undervoltage, unbalance voltage, staggered phase protection.
LCD display shows voltage, fault status, parameter setting.
Adjustable overvoltage value (390-490V), undervoltage value (300-370 V), voltage imbalance range(5%-29%) and action time (0.1-25s).
The meter can be installed on a 35 mm DIN rail
