The differential and minimum DMR-400T relay is intended for connection of generators to an onboard network when their tension exceeds bortseta tension (on 0,2 — 0,7 In), automatic disconnection of the generator from a bortseta at the return current (for example, 15-35 A for DMR-400T) and exceptions of a possibility of turning on of the generator in a network with the return polarity.
Besides, the differential and minimum relay automatically switches-off the generator at break of a power wire between the generator and the differential and minimum relay at a certain scheme of external inclusions and provides manual (non-automatic) remote turning on and shutdown of the generator.
Now use the differential and minimum DMR-200, DMR-400, DMR-600, DMR-800 relays
Figures in designation of the relay of each type correspond to rated currents on which power contacts of the relay (200, 400, 600, 800 And), and letters after figures — to their modifications are calculated (for example, DMR-400AM, DMR-400D etc.).
