Macromatic Protects Motor From Premature Failure

Macromatic redesigns DIN-rail Mounted Three-Phase Monitor Relay to protect equipment from voltage faults.

Macromatic redesigned the PMD Series, a Three-Phase Monitor Relay for DIN-rail mounting, which provides protection for motors from phase loss, phase reversal, undervoltage, overvoltage and phase unbalance conditions along with rapid cycling.

PMD Series Three-Phase Monitor Relay

Macromatic redesigned the PMD Series Three-Phase Monitor Relay to offer unique functionality with a variety of options while keeping it easy to use:

  • Universal voltage range of 190-500V-greater range that covers more global applications (a separate 480-600V version is also available)
  • Retains fault indication and continues monitoring all voltages even with a lost phase
  • Best-in-class phase loss protection
  • True RMS voltage measurement ensures accurate sensing across more applications
  • Full fault indication on top of unit for easy troubleshooting
  • Manual reset option works with external switch-to reset the relay from outside the enclosure
  • DPDT output contacts
  • Mounts on 35mm DIN-rail
  • Meets IEC enclosure design standards
