Description
The Littelfuse 202 Voltage Monitor is a three-phase auto-ranging voltage monitor that is intended for use in protecting motors that operate at 190-480 VAC at 50/60 Hz. It continuously supervises voltage conditions and any abnormalities such as low/high voltage, phase reversal, and unbalance. In the case of adverse conditions, the output relay of the part is turned off after a trip delay to minimize risks. This monitor is suitable for HVAC equipment like fan motors, scroll compressors, grinders, conveyors, elevators, and escalators.
