Littelfuse 460-L Adjustable Voltage Monitor 190-480V 3PH

The Littelfuse 460-L 3PH Voltage Monitoring Relay is an electronic device that protects three-phase motor in HVAC systems by checking voltage level. This device protects motors from damage by monitoring voltages between 190 and 480V. It identifies phase loss, phase reversal, unbalanced phases, low voltage and high voltage to stop equipment breakdowns. This device protects air conditioning units and other equipment by detecting faults and shutting them down automatically before restarting once conditions return to normal. The device helps motors run longer while saving on maintenance and improving system performance. It protects HVAC systems from electrical issues to maintain proper operation in commercial and industrial environments.
