The 460 series is a three-phase voltage monitor that protects 190-480 V ac or 475-600 V ac, 50/60 Hz 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. All 460 models feature an adjustable 1-30 second trip delay, 1-500 second restart delay, 2-8 % voltage unbalance trip point, and one form C contact except where noted on the datasheet.

功能与特色

  • Auto-sensing wide voltage range
