339-E-P5-G5-H-E-S-N-N-SN-D-N

Short Description: The 339-E-P5-G5-H-E-S-N-N-SN-D-N is a GE Multilin 339 motor protection relay, offering integrated motor protection, metering, monitoring and control for medium and large industrial motors.

Product Description

The 339-E-P5-G5-H-E-S-N-N-SN-D-N is part of GE Multilin 339 series motor protection relay. It combines motor fault protection, electrical parameter measurement, event logging and communication capabilities into a single compact device. This relay protects motors against common electrical faults and abnormal operating conditions, records fault waveforms and operational events for post-fault analysis. With flexible hardware configurations and built-in HMI, it can be seamlessly integrated into industrial control and SCADA systems, suitable for new installations and legacy system retrofits.

Key Functions

• Full motor protection: overload, locked rotor, overcurrent, earth fault, phase unbalance, overvoltage and undervoltage protection
• High precision metering of current, voltage, power, power factor and energy consumption
• Fault waveform capture, event recording and fault sequence reporting for troubleshooting
• Multiple communication protocols to connect with SCADA and DCS for remote monitoring
• Local HMI for parameter configuration, status display and manual control operation

Applications

• Medium and large motor protection in industrial plants
• Oil & gas, petrochemical, mining and water treatment pumping stations
• Power plant auxiliary motor control and protection cabinets
• Manufacturing factory heavy-duty motor control centers (MCC)
• Replacement, maintenance and upgrade for existing Multilin 339 relay systems
