Description
Littelfuse® Symcom Voltage Monitoring Relay, 3-Phase, Series: 250A, 475 to 600 V AC, 50/60 Hz, 2 Form C DPDT, Threaded Mount, 2/4 s Trip Delay, 2.93 in H x 5.27 in W x 2.95 in D
Features:
- Proprietary microcontroller based circuitry, constant monitoring of 1-phase, low voltage, voltage unbalance, phase reversal, harmful power line conditions
- 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, LED indications include, normal operation, power-up restart delay, reverse phase trip, unbalance/single phase trip, high or low voltage trip
- Adjustable trip delay prevent nuisance tripping due to rapidly fluctuating power line conditions
- DPDT relay output, allows for versatility to meet wide application needs
- Manual reset, allows for inspection of equipment before system is re-energized
- 4 s low voltage, high voltage and 2 s unbalance, phasing fault trip delay time
- Provides high and low voltage protection at fixed percentage of nominal voltage
