3-phase monitoring relay for detection of incorrect phase sequence,total and partial phase loss.

The device detects regenerated voltage up to 85% of the nominal voltage(phase-phase).

• 3-phase monitoring relay for phase sequence and phase loss
• Detects when all phases are present and have the correct sequence
• Measures own power supply
• Power supply range: 288 to 460 VAC (±15%, Ph-N)
• Output: 5A SPDT relay normally energized
• For mounting on DIN-rail in accordance with DIN/EN 50 022
• 17.5mm DIN-rail housing(DIN 43880)
• LED indication for relay and power supply ON
• Automatic protect once N-line is broken
