About the 345-E-P1-G1-H-E-S-N-N-1E-N-N
General Information
The 345-EP1G1HESNN1ENN is a transformer protection relay in GE Multilin's 345 series. This unit can provide protection, control, and management to small or medium sized power transformers. Programmable logic allows this unit to serve a wide range of applications. Models in this series were created from a list of optional components. This model is relatively standard when compared to the baseline of this series.
Relay Functionality
One of the main strong points of the 345-EP1G1HESNN1ENN is its communications package. This package includes support for Ethernet as well as IEC 60870-5-104, DNP3.0, and Modbus TCP/IP protocols. This unit has the less-common 1A ground and three-phase inputs as well as a high-voltage 110-250VDC/110-230VAC power supply. This model has all the standard current protections from this series, which include percent differential among other key protections.
Environmental Ratings
The 345-EP1G1HESNN1ENN has a non-drawout case design and does not have harsh environment conformal coating. This unit is rated for an operating temperature range of -40 to 60°C and a storage temperature range of -40 to 85°C. This unit is rated for humidity levels up to 95% non-condensing at a temperature of 55°C. This model is rated for pollution degree II environments and a maximum altitude of 2000 meters.
