Description
The Littelfuse 460-14 Adjustable Voltage Monitoring Relay is a 3-phase protection part designed for industrial electrical systems operating in the 190–480V range. It continuously monitors voltage conditions such as overvoltage, undervoltage, phase loss, phase reversal, and voltage imbalance, helping prevent damage to connected motors and control equipment. Commonly applied in HVAC installations, it ensures that compressors and blower motors operate only under safe electrical conditions. Installed within control panels, it responds to abnormal power supply variations by triggering a relay output, which helps maintain system reliability and protect essential components from electrical faults.
