As long as the monitored voltage (Un) remains within the OVER (Umax) & UNDER (Umin) voltage settings, the internal relay stays energized. If the monitored voltage falls outside this range, the relay will drop-out. The Umax dial sets the upper limit per the Overvoltage range of the product. The Umin dial sets the lower limit at 30-95% of the upper setting. This product has an adjustable time delay on drop-out of 0.1-10 seconds (t) to prevent nuisance tripping.

Over/Under Voltage Relays provide protection to equipment where either an over or under voltage condition is potentially damaging. They are designed to operate when the operating voltage reaches a preset value and drop-out when the operating voltage drops to a level below the preset value.
