About the 350-E-PX-GX-H-E-N-N-V-2E-N-H
Overview
The 350-EPXGXHENNV2ENH is a high-voltage feeder protection relay from GE Multilin in the 350 series. This relay offers management, protection, and control capabilities to industrial and utility feeder applications. This series was designed to work with low, medium, and high-voltage feeder systems as either primary or backup protection. This unit was made-to-order from a list of optional features that suit it for particular environments and scenarios over others.
Voltage and Frequency
The main feature that sets the 350-EPXGXHENNV2ENH apart from most of its contemporary models on the market is its lack of current transformers. The protection features in this unit are built around voltage and frequency. These protections include things like phase/auxiliary undervoltage, phase/neutral/auxiliary/negative sequence overvoltage, over frequency, under frequency, vt fuse fail, and volts per hertz. This unit also has voltage metering functionality.
Other Features
The 350-EPXGXHENNV2ENH has advanced communications features which include copper and fiber Ethernet and IEC 61850 GOOSE, DNP3.0, and Modbus TCP/IP protocol support. This unit has the series-standard control features of cold load pickup and lockout relay. For I/O capabilities, this model has 10 contact inputs, 2 Form A outputs, and 5 Form C outputs. This model uses a 125-250VDC/120-240VAC power supply and a non-drawout case design. This model does not include harsh environment conformal coating.
