GE Multilin 339-C-P5-G5-H-E-S-N-P-3E-D-N Motor Protection Relay

General Information

The 339-EP1G1HESNN3EDN is a relay designed for protection, management, and control of low and medium-voltage industrial motors. This unit was designed by GE Multilin as part of their 339 series of made-to-order motor protection systems. This means that this model and others from this series were configured with a specific set of features when they were initially ordered. For example, this unit has 1A ground and three-phase current inputs. If you would like to see the full list of specs for this model, see the attached naming guide in the “Manuals” section of this page.

Key Features

Some of the more notable features of the 339-EP1G1HESNN3EDN include its case design, communications, and inputs/outputs. The drawout case design that this model uses is invaluable in reducing system downtime for things like maintenance and testing. This unit has an advanced communications feature set, which includes all the standard features plus Ethernet Modbus TCP/IP, DNP3.0. IEC 61850, and IEC 60870-5-104. This model has 10 contact inputs as well as 2 Form A and 5 Form C outputs.

Environmental Information

The 339-EP1G1HESNN3EDN is a high-voltage unit with a 110-250VDC/110-230VAC power supply. This unit has the standard array of extensive current protections. These protections include features like undercurrent, thermal overload, phase/neutral/ground overcurrent, and much more. This unit is not coated with the optional harsh environment conformal coating, so it may be more susceptible to particularly harsh industrial situations than others in this series.
