The UVR-21-V2 is a three-phase under-voltage control relay designed to protect electrical equipment from low voltage conditions and long-term voltage fluctuations. It monitors the supply voltage of 415V AC three-phase systems and controls the relay output according to the voltage status and delay time. With delayed under-voltage protection, LED indication, and DIN rail mounting, it is suitable for voltage monitoring and protection in control panels, distribution circuits, and three-phase electrical equipment.
