Three Phase Voltage Monitoring Relay

The Three Phase Voltage Monitoring Relay is designed to protect electrical systems from over-voltage, under-voltage, phase failure, phase sequence, and phase asymmetry conditions. It continuously monitors supply voltage in 3-phase 3-wire and 3-phase 4-wire systems, ensuring safe and reliable operation of equipment. With adjustable voltage settings, LED status indicators, DIN-rail mounting, and dual changeover relay outputs, this relay is ideal for applications such as panels, generators, motors, HVAC systems, lifts, and industrial automation. Its compact 35 mm design makes it easy to install in control panels while meeting CE and RoHS compliance standards.
