Product Title

GE 369‑HI‑R‑0‑0‑0‑0‑E – Multilin 369 Motor Management & Protection Relay

Product Overview

The GE 369‑HI‑R‑0‑0‑0‑0‑E is an advanced motor management and protection relay manufactured by GE Multilin. Designed for medium‑size three‑phase AC motors, this relay combines comprehensive protective functions with enhanced monitoring, diagnostics, and control capabilities. It is used in industrial settings where reliable motor performance and fault prevention are critical, such as manufacturing plants, water treatment facilities, and heavy‑duty process systems.

This model features HI control power (wide range DC/AC supply), R‑level built‑in RTD inputs for temperature monitoring, and E enhanced diagnostics and faceplate options that provide deeper insight into motor health and system events. With integrated communication interfaces and configurable settings, the GE 369‑HI‑R‑0‑0‑0‑0‑E supports both protection and operational analytics.
