Description
The Littelfuse 460L-OEM Adjustable Relay Volt Monitor is a three-phase voltage monitoring part that is used to protect motors that operate at 190-480 VAC or 475-600 VAC, 50/60 Hz. It constantly checks voltage conditions such as low voltage, high voltage, and unequal voltage, phase loss, and phase reversal. It does not trip under any other adverse conditions and resets itself once normal conditions are restored hence does not trip unnecessarily. This monitor is suitable for HVAC systems and industrial use with adjustable trip delay of 1-30 seconds and restart delay of 1-500 seconds to ensure the protection and of the equipment. It will also help in increasing the motor longevity, cutting on time not in operation and increasing operation safety.
