Description
Littelfuse® Voltage Monitoring Relay, 3-Phase Auto Ranging Dual Range, Series: 201A-AU, 190 to 480 V AC, 50/60 Hz Frequency, 1 Form C SPDT Contact Configuration, 8 Pins, DIN Rail/Surface Mounting, 1 to 30 s Trip Delay, 1-3/4 in H x 2-3/8 in W x 4-1/8 in D Dimensions
Features:
- Proprietary microcontroller based circuitry, constant monitoring of loss of any phase, low voltage, high voltage, voltage unbalance, phase reversal, rapid cycling, harmful power line conditions
- Compact design for 8-pin DIN rail or surface mount, allows flexibility in panel installation
- Auto-sensing wide voltage range, automatically senses system voltage between 190 to 480 VAC, saves setup time
- Advanced LED diagnostics, quick visual indicator for cause of trip
- Adjustable voltage unbalance trip setting, allows compatibility with a variety of motors and reduces nuisance tripping
- Adjustable trip & restart delay settings, prevent nuisance tripping due to rapidly fluctuating power line conditions
