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 DPA01D PPA01 Product Description 3-phase relay for detection of incorrect phase sequence, total and partial phase loss. Supply range from 208 to 480 VAC covered by one multivoltage relay (or by two multivoltage relays for DPA01D Ordering Key DPA 01 C M44 models). For mounting on DIN-rail or plug-in module. The device detects regenerated voltages up to 70% of the mains nominal voltage (phase-neutral).

The relay operates when all the phases are present and the phase sequence is correct. The relay releases when one phase-neutral voltage drops below 70% of the other phase-neutral voltages. Example 1 The relay monitors that the power supply has the correct phase sequence and that all phase voltages are present. Example 2 The relay releases in case of interruption of one or more phases, provided that the regenerated voltage does not exceed 70% of the mains phase-neutral voltage.
