      Broyce Control
      Broyce Control Phase, Voltage Monitoring Relay with DPDT Contacts, 3 Phase, 280 → 520 V ac
      Product Details

      M3PRT/2 & M3PRT/2-4W Phase Failure, Phase Sequence & Under Voltage plus Time delay

      35mm DIN rail housing
      Microprocessor controller with internal monitoring (self-checking)
      Monitors own supply and detects an under voltage condition on one or more phases
      M3PRT/2 measures phase-to-phase voltage and M3PRT/2-4W measures phase-to-neutral voltage
      Instantaneous cancellation of set time delay when 70% of Un is reached during under-voltage condition
      Detects incorrect phase sequence, phase loss and neutral loss (4-wire only)
      Adjustment for under-voltage trip level
      Adjustment for time delay (from an under-voltage condition)
      1 x DPDT relay output 8 A@250Vac
      Intelligent LED indication for supply and relay status
      Power on delay (Td) : 1s (worst case = Td x 2)

      Phase Sequence/Failure Relays

      Monitoring of 3 phase supplies
      Orange housing manufactured to DIN 43 880
      DIN rail mount
