UAS-0 three-phase monitor relay

UAs-0 típusú háromfázisú feszültségrelé The UAS-0 type three-phase voltage monitor is suitable for protection of three-phase loads (mainly motors) against phase-asymmetry and faulty sequence on line voltage.
The monitor relay operates reliably too in case of distorted sinusoidal line voltage, occurred by inverters or switching power supply units.
