Broyce Control
Broyce Control Phase, Voltage Monitoring Relay with DPDT Contacts, 3 Phase, 400 V ac
Product Details

M3PRC/S/2 & M3PRC/S/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 if one or more phases exceed the set under or over-voltage trip levels
M3PRC/S/2 measures phase to phase voltage and M3PRC/S/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 and over voltage trip levels
Adjustment for time delay (from an under or over voltage condition)
1 x DPDT relay output 8A
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
