The E1PF400VSY01 is a compact three-phase monitoring relay designed to ensure the stability and safety of electrical systems. Operating at a supply voltage of 400V AC, it monitors phase sequence, detects phase failures, and offers adjustable asymmetry monitoring between 5% and 25%, allowing for tailored protection against voltage imbalances. The optional neutral wire connection enhances…
