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
