Description

LittelfuseĀ® Symcom Voltage Monitoring Relay, 3-Phase, Series: 250A, 190 to 480 VAC, 50/60 Hz Frequency, DPDT 2-Form C Contact Configuration, Threaded Mounting, 2/4 s Trip Delay, 5.27 in W x 2.95 in D x 2.93 in H Dimensions

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

Standards/Approval:

  • 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
