- 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
- UL 508 File No. E68520|CSA C22.2 File No. 14/46510|CE IEC 60947-6-2|IEC 68-2-3|PROP65: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer
