About the 339-E-P5-G5-L-E-S-N-N-SN-N-N
Overview
The 339-EP5G5LESNNSNNN is a low-voltage model is a GE Multilin motor protection relay in the 339 series. This unit was designed to work with low and medium-voltage motors and is particularly towards the baseline in terms of which optional features are present. This is most apparent when it comes to the non-drawout case design and lack of harsh environment conformal coating. Operators who are looking for a motor protection relay like this one should keep in mind the limitations on the level of environmental hazards this unit can handle compared to a conformal coated model.
Operational Features
The 339-EP5G5LESNNSNNN has 5A inputs for both ground and three-phase currents. Additionally, this model has 10 contact inputs as well as 2 Form A and 5 Form C outputs. This model uses the standard current protection package for this series, which includes undercurrent relay, locked/stalled rotor, locking-out relay, neutral/phase time overcurrent, breaker failure, and many more crucial protections. The standard communications package found on this model contains a front USB and a rear RS485 that supports DNP3.0, IEC 60870-5-103, and Modbus RTU.
Miscellaneous Information
The 339-EP5G5LESNNSNNN uses a low-voltage 24-48VDC power supply. This unit is programmed in English and does not have programmable LEDs. Setting up this unit is quick and straightforward thanks to the EnerVista setup software and tools like the Motor Settings Auto-Configurator.
