Product Title

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

Product Overview

The GE 369‑HI‑R‑0‑0‑0‑E is a multifunction motor protection and management relay from the GE Multilin 369 series, designed to protect three‑phase AC motors and associated electrical systems. This solid‑state relay integrates protection, metering, diagnostics, and control into a single unit — ensuring safe, reliable operation of motors in industrial, commercial, and utility environments.

The “HI” in the model designator indicates wide control power capability, and “E” denotes an enhanced feature set such as extended monitoring outputs or configuration options. The relay continuously measures electrical quantities such as current, voltage, and frequency, and applies configurable protective elements to prevent damage due to overloads, short circuits, ground faults, and other abnormal conditions. Its capabilities extend beyond protection to include real‑time metering and diagnostics, enabling improved asset visibility and reduced unplanned downtime.

Main Features and Benefits

Integrated Motor Protection:
The 369‑HI‑R‑0‑0‑0‑E consolidates multiple protective elements (overcurrent, thermal, imbalance, phase loss, etc.) into a single device, reducing hardware cost and panel space while offering comprehensive safety coverage.

Real‑Time Metering & Monitoring:
Real‑time metering of current, voltage, power, and frequency enables operators to view equipment status locally or via communication networks, aiding in preventive maintenance and performance analysis.

Configurable Protective Logic:
User‑programmable settings allow tailored thresholds for trip elements, minimizing nuisance trips while ensuring protection for specific motor and load conditions.

User‑Friendly Interface:
The local LCD display provides clear indication of system conditions, alarms, and fault history, enabling faster troubleshooting and fewer manual interventions.

Application Scenarios

Industrial Motor Protection:
Ideal for guarding motors in pump systems, compressors, fans, conveyors, and other critical loads against electrical faults.

Process Industries:
Used in petrochemical, chemical, and manufacturing plants where motors form part of critical process loops requiring reliable protection and monitoring.

Water & Wastewater Treatment:
Protects motors driving pumps and aerators, ensuring continuous operation and rapid fault response.

Energy & Utilities:
Applied in power generation support systems, such as cooling fans and auxiliary equipment, to maintain reliability and reduce downtime.
