Leakage relay RU-127/220.1 M (PN-127/220, WAKE-127)
Leakage relay is designed to protect people from electric shock and prevent dangerous effects of leakage current to the ground in three-phase AC voltage 127V or 220V with isolated neutral of the transformer by reducing the total insulation resistance to a dangerous extent. Leakage relay has the self-control of health basic circuit elements, and automatic adaptation to the voltage of the protected circuit 127 or 220 C.
The relay works in the mines, hazardous gas and dust, when the ambient temperature from minus 10 °to 35 ° C and relative humidity up to 98% at 35°C.
