Carlo Gavazzi DPA01 / PPA01 Series Monitoring Relay

• Detects when all three phases are present and in proper sequence
• Measures its own power supply
• 208 to 600 VAC power supply range
• 8A SPDT or 8A DPDT relay output
• 22.5mm wide DIN-rail mount housing or plug-in module
• LED indication for power supply and output relay and ON

The Carlo Gavazzi DPA01 / PPA01 Series monitoring relay is a three-phase monitoring relay used for detection of incorrect phase sequence, and total or partial phase loss. The relay has no user adjustments or settings, making it simple to set up and easy to use. The DPA01 is DIN-rail mountable, and the PPA01 mounts on a plug-in module. Both feature diagnostic LEDs. The monitoring range of 208 to 600 VAC is covered by two multi-voltage relays. The device detects regenerated voltages up to 85% of the nominal voltage (phase-phase). The DPA01 / PPA01 series relay protects motors and other 3-phase powered machinery from the damaging and dangerous effects of phase anomalies.
