Monitoring Relays
3-Phase Sequence and Phase Loss
Type DPA53
• 3-phase monitoring relay for phase sequence and phase loss
• Detects when all phases are present and have the cor- rect sequence
• Knob-adjustable undevoltage detection
• Measures its own power supply
• Power supply range: 208 to 240 and 380 to 480 VAC (±15%)
• Output: 5 A SPDT relay normally energized
• For mounting on DIN-rail in accordance with
DIN/EN 50 022
• 17.5 mm DIN-rail housing (DIN 43880)
• LED indication for relay and power supply ON
Product Description Ordering Key
