Three Phase Monitoring Relays or Protective Relays, protect motors and equipment from expensive damage due to voltage faults on three-phase systems. Refer to the table below for more information on the level of protection offered by each product, then click one of the Series to see details about a specific product type.
The PCP Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase reversal. These products have an isolated relay output that is only energized if the three phases are in the proper A-B-C sequence. The relay output will remain open if any two phases are reversed...
The PLP Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss and phase reversal. These products detect single phasing regardless of any regenerative voltages.
The PAP Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal and undervoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages...
The PJPU-FA8X Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal & undervoltage. They also provide an indication of a phase unbalance condition, but the relay does not trip.These products detect single phasing and unbalanced voltages regardless of any regenerative voltages.
The PMP Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages...
The PMPU-FA8 Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages...
The PMPU-FA8X & PMPU-FA12X Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages...
The PMD Series Three-Phase Monitor Relays continuously monitor all voltages to protect motors and equipment from expensive damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing and unbalanced voltages regardless of any regenerative voltages...
The PBDU Series Phase Monitor Relays protect motors and equipment from damage due to voltage faults on three-phase systems. PBDU relays monitor phase loss, phase reversal, and unbalance. Phase unbalance is adjustable from 5% to 25%, and can be disabled altogether if desired...
PC Series Three-Phase Monitor Relays protect equipment from voltage faults and communicate via Modbus TCP. This industry-leading technology makes data available for continuous monitoring, real-time alerts and intelligent troubleshooting of voltage systems.
