GE Multilin 369-HI-R-M-0-P-0-E Motor Management Relay

Overview

The GE Multilin 369-HI-R-M-0-P-0-E is a motor protection relay built for medium-sized AC motors. It combines protection, monitoring, and control in one compact unit. Although GE has discontinued the 369 series in favor of newer models like the GE 859, it remains widely used due to its reliability and proven design. This relay helps prevent motor failures and improves operational efficiency through real-time diagnostics and flexible configuration options.
