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.
