Overview
339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
Introduction
The 339 Motor Protection System is a microprocessor based relay providing suitable
protection of medium voltage motors. The small footprint and the withdrawable option
make the 339 relay ideal for panel mounting on either new or retrofit installations. The
combination of proven hardware, a variety of protection and control features, and
communications, makes the relay ideal for total motor protection and control. Equipped
with serial (RS485), USB, and Ethernet ports, and a wide selection of protocols such as
Modbus, DNP3.0, IEC 60870-5-103, 60870-5-104, GOOSE, the 339 relay is the best-in-class
for MCCs, SCADA and inter-relay communications. The 339 relay provides excellent
transparency with respect to power system conditions and events, through its four-line
20-character display, as well as the EnerVista 3 Series Setup program. Conveniently
located LEDs provide indication of overall relay operation, as well as alarm, pickup, and
motor status.
The 339 relay provides the following key benefits:
•
Withdrawable small footprint – saves on rewiring and space.
•
Fast setup (Quick Setup) menu provided, to guide users through a wide range of motor
management applications.
•
Large four-line LCD display, LEDs, and an easy-to-navigate keypad.
•
Multiple communication protocols for simultaneous access when integrated into
monitoring and control systems.
