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
