Three-Phase Monitor Relays are available with plug-in or Din-rail enclosures that offer protection from a combination of voltage faults: Phase Loss, Phase Reversal, Phase Unbalance, Under Voltage, or Over Voltage. These relays are compatible with most Wye or Delta systems with no connection to neutral required. Take a quick look at these popular products from Macromatic, PMPU in the PMP Series, and PMDU in the PMD Series.
PAP, PCP, PLP and PMP Series with plug-in enclosures use standard 8 pin octal sockets. These relays have a wide universal voltage range for use in more global applications.
PBDU Series (17.5 mm wide) and PMD Series (52.5 mm wide) mount on 35 mm DIN-rail. Both can be panel mounted with two screws by extending the black clips from under the relays. Full fault indication on top of units facilitates easy troubleshooting.
PC1 WITH COMMUNICATION – DIN-RAIL
Relays protect and communicate fault conditions with Modbus TCP to reduce downtime and service costs. These relays improve decision making within smart control systems. Real-time and historical data is available for alerts, predictive maintenance, and troubleshooting.
