- Phase Failure (Phase Loss): Instantly detects if one of the three phases goes completely dead or falls below fixed operational thresholds, preventing motors from "single-phasing" (which causes catastrophic winding burnouts).
- Phase Sequence: Ensures that the physical phase rotation matches the expected sequence (L1-L2-L3). If the rotation is reversed, the relay trips to prevent industrial equipment—like motors, pumps, and compressors—from spinning backwards and destroying themselves.
