Monitoring Relays
3-Phase Sequence and Phase Loss
Types DPA01, PPA01
• 3-phase monitoring relays for phase
sequence and phase loss
• Detect when all 3 phases are present and have the
correct sequence
• Measure on own power supply
• Power supply range: 208 to 480 VAC (±15%)
• Output: 8 A SPDT relay or 8 A DPDT normally energized
• For mounting on DIN-rail in accordance with DIN/EN
50 022 (DPA01) or plug-in module (PPA01)
• 22.5 mm Euronorm housing (DPA01) or 36 mm plug-in
module (PPA01)
• LED indication for relay and power supply ON
