VSP D1 minilec phase failure relay

VSP D1 Minilec Phase Failure Relay

This VSP D1 minilec phase failure relay is a Phase control relay. The voltage measurement range is 0.15VAC to 10VAC. It monitors phases and the presence of voltage on the 3 phases of a 3 phase circuit power supply. It indicates also any phase loss or inversion. It supplies 1 fail-safe change-over contact. The parameter setting is done on the front panel by direct scale by using a screwdriver. It could be used for example to control the power supply of a 3-phase motor. The precision of the display is +/- 10% of the full scale. The time delay on tripping is 0.3s.
