About the 345-E-P5-G5-H-E-M-N-N-2E-N-N

General Information

The 345-EP5G5HEMNN2ENN is a 345 series transformer protection relay from GE Multilin. This unit is designed to provide protection, management, and control to power transformers in utility or industrial situations. This unit may provide protection in various applications such as autotransformers, distribution transformers, two winding power transformers, and reactors. This is a high-voltage model of relay with a 110-250VDC/110-230VAC power supply.

Unit Features

The 345-EP5G5HEMNN2ENN has advanced communication and current protection feature sets. This unit's communication package includes the standard front USB and rear RS485 ports alongside Ethernet and additional supported protocols. These protocols include Modbus TCP/IP, IEC 60870-5-104, and IEC 61850 GOOSE. The advanced current protections on this model include breaker failure and restricted ground fault along with all the standard protections like percent differential protection. This unit has 5A inputs for 3-phase and ground currents.

Quality Features

The 345-EP5G5HEMNN2ENN can provide protection for two winding power transformers, reactors, autotransformers, and distribution transformers. Upon manufacture, this unit was subjected to accelerated life testing to confirm that it would be a durable and reliable unit. Being created from automotive grade components, this unit is high quality and has a long life cycle. One durability feature that is not present in this model is the optional harsh environment conformal coating, which would improve longevity in particularly difficult conditions.
