Littelfuse 460-L Voltage Monitor 3-Phase 190-480VAC

Product Description

The Littelfuse 460-L Voltage Monitor is crafted to shield motors ranging from 190-480VAC and 475-600V, across all sizes, from detrimental voltage discrepancies. Employing advanced microcontroller-based sensing, this device continuously scrutinizes three-phase voltages. It addresses issues such as voltage imbalance, phase loss, and phase reversal by deactivating its output relay when abnormalities are detected, subsequently reactivating when normal conditions are restored.

• Automated sensing of line voltage
• Adjustable 1 to 30-second trip delay
• Enhanced reliability with a 1 to 500-second restart delay
