460

460 is a three-phase voltage monitor that protects motors regardless of their size. This voltage monitor provides a user-selectable nominal voltage setpoint and will automatically sense line voltage. A unique microcontroller-based voltage and phase-sensing circuit constantly monitors the three-phase voltage to detect harmful power line conditions such as low, high, and unbalanced voltage, loss of any phase, and phase reversal. When a harmful condition is detected, the MotorSaver® output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for a specified amount of time (restart delay). The trip and restart delays prevent nuisance tripping due to rapidly fluctuating power line conditions. Typical applications include oil rigs, compressors and fans, HVAC, heat, well and sump pumps, small conveyor motors.
