1.1 Overview
1.1.1 239 Relay Features
The GE Multilin 239 relay is designed to fully protect three phase AC motors against
conditions which can cause damage. In addition to motor protection, the relay has
features that can protect associated mechanical equipment, give an alarm before
damage results from a process malfunction, diagnose problems after a fault and allow
verification of correct relay operation during routine maintenance. Using the ModBus serial
communications interface, motor starters throughout a plant can be connected to a
central control/monitoring system for continuous monitoring and fast fault diagnosis of a
complete process.
One relay is required per motor. Since phase current is monitored through current
transformers, motors of any line voltage can be protected. The relay is used as a pilot
device to cause a contactor or breaker to open under fault conditions; that is, it does not
carry the primary motor current. When the over temperature option is ordered, up to 3

CHAPTER 1: OVERVIEW
RTDs can be monitored. These can all be in the stator or 1 in the stator and 2 in the
bearings. Installing a 239 in a motor starter for protection and monitoring of motors will
minimize downtime due to process problems.

CHAPTER 1: OVERVIEW
1.1.2 Typical Applications
Versatile features and simple programming controls make the 239 an ideal choice for
motor and equipment protection in a wide range of applications. In addition to basic
electrical protection for motors, the 239 can protect against common faults due to process
problems, such as:
1. Mechanical protection of pumps using the undercurrent feature to detect loss of
suction or a closed discharge valve.
2. Mechanical protection of fans against loss of air flow in mines or flow in steam
generating boilers using the undercurrent feature.
3. Electrical protection of compressor motors from excessive run up time caused by an
open outlet using the start timer.
4. Mechanical protection of gears, pumps, fans, saw mill cutters, and compressors
against mechanical jam using the mechanical jam trip feature.
5. Safety to personnel from shock hazard using the ground fault feature to detect
winding shorts from moisture.
6. Protection of motors and equipment from operator abuse using the thermal memory
lockout.
Cost savings are provided using versatile features such as:
1. Diagnostic information after a trip to identify problems and bring the process back on
line quickly.
2. Fault indication of ground fault without shutdown to warn that corrective
maintenance is required.
3. Simplified spare parts stocking and initial specification design using one universal
model for many motor sizes, applications and settings.
4. Serial communication using the popular Modbus protocol to remotely monitor all
values, program setpoints, issue commands and diagnose faults to minimize process
disruptions.
5. Output of motor current suitable for programmable controller interface (4 to 20 mA).
