The GE Multilin 369-HI-R-0-0-0-0-E is a compact, high-performance motor protection relay designed for medium-sized AC motors (20–100Hz) in industrial and commercial applications. It integrates advanced protection, monitoring, and control functions with high-range control power (HI: 50–300V DC/40–265V AC), 12 built-in RTD inputs (R), and enhanced diagnostics (E module). Ideal for variable frequency drive (VFD) and two-speed motor applications, it ensures reliable motor operation while minimizing downtime and maintenance costs.
