GE Multilin 369-HI-R-B-0-D-0-E 369 Motor Protection System

General Overview

The GE Multilin 369 Motor Management Relay is a digital relay designed to protect and monitor three-phase motors and their associated mechanical systems. It has the unique ability to ‘learn’ individual motor parameters, such as motor inrush current, cooling rates, and acceleration time, to enhance its protective capabilities.

Key Features

• Protection and Monitoring: Offers protection where other relays cannot, using the FlexCurve™ custom overload curve or one of fifteen standard curves.
• Communication Ports: One RS232 front panel port and three RS485 rear ports with standard Modbus RTU protocol.
• Input Methods: Setpoints can be entered via the front keypad or EnerVista 369 Setup software.
• Status Display: Displays status, actual values, and troubleshooting information via the front panel or through communications.
• RTD Monitoring: Optional monitoring for up to 12 RTDs from the stator, bearings, ambient, or driven equipment, with a remote RTD module available as an accessory.
• Metering Package: Optional package with VT inputs for voltage and power elements, metering V, kW, kvar, kVA, PF, Hz, and MWhrs. Includes three additional user-configurable analog outputs.
