GE Multilin 239‑RTD‑AN Motor Protection Relay

Overview

The GE Multilin 239‑RTD‑AN is a high‑performance, compact motor protection relay designed for comprehensive safeguarding of three‑phase AC motors (small to medium size) in harsh industrial environments. It integrates advanced thermal protection via RTD inputs, electrical fault detection, and communication capabilities, making it ideal for pumps, conveyors, compressors, fans, and mining equipment. The AN suffix denotes a single isolated analog output for flexible system integration.

 

Key Features

1. Comprehensive Protection Functions

• Thermal Overload: 15 selectable curves, thermal memory lockout, overtemperature protection via 3 RTD inputs (Pt100/Pt1000, Ni120, Cu10).
• Electrical Faults: Short circuit, locked rotor, single‑phasing/current unbalance, ground fault (trip/alarm), undercurrent, breaker failure.
• Voltage Protection: Undervoltage/overvoltage monitoring (200–690 V).

2. Advanced Monitoring & Control

• RTD Temperature Monitoring: Supports stator/bearing RTDs, operating range ‑40°C to +200°C.
• Real‑Time Data: 40‑character illuminated LCD display for status, current, temperature, and fault diagnostics; 6 LED indicators.
• Fault Recording: Stores last 5 trip records for post‑fault analysis.
• Analog Output: 1 isolated analog output (AN option) for temperature or current signaling.

3. Communication & Connectivity

• RS485 Serial Port: Supports Modbus RTU protocol for remote monitoring and configuration.
• EnerVista Software: Compatible with GE’s EnerVista setup software for easy programming and maintenance.

4. Mechanical & Environmental

• Compact Design: 110 × 55 × 30 mm, approx. 0.5 kg; fits most motor starters.
• Harsh Environment: IP67 rating, conformal coating option; operating temperature ‑40°C to +70°C.
• Certifications: UL, CSA approved for global industrial use.

Technical Specifications

Applications

• Industrial Motors: Pumps, fans, compressors, conveyors (manufacturing, oil & gas, mining, water treatment).
• Harsh Environments: High/low temperature, dust, moisture (IP67).
• Critical Equipment: Multi‑speed motors, process machinery requiring precise thermal protection.
