Monitoring Relays
True RMS 3-Phase, 3-Phase+N, Multifunction
Types DPC71, PPC71
• TRMS 3-phase over and under voltage,
phase sequence, phase loss, asymmetry and tolerance monitoring relay
• Detect when all 3 phases are present and have the correct sequence
• Detect if all the 3-phase-phase or phase-neutral voltages are within the set limits
• Detect if asymmetry and tolerance are within the set value
• Separately adjustable setpoints
• Separately adjustable delay functions (0.1 to 30 s)
• Output: 2 x 5 A relay SPDT NE
• For mounting on DIN-rail in accordance with
DIN/EN 50 022 (DPC71) or plug-in module (PPC71)
• 35.5 mm Euronorm housing (DPC71) or 35.5 mm plug- in module (PPC71)
• LED indication for relays, alarm and power supply ON
