About the 345-E-P1-G1-H-E-S-N-N-SN-D-N

Summary

The 345-EP1G1HESNNSNDN is a high-voltage GE Multilin transformer protection relay. This unit may provide control, management, and primary or backup protection of power transformers. As a member of the 345 series, this unit was originally made-to-order from a list of optional feature sets. This particular model's most notable features are its 1A current inputs and drawout case design. Aside from these features, this model has the most basic feature sets chosen for other functions like communications and current protection.

Standard Features

As mentioned, the 345-EP1G1HESNNSNDN has standard feature sets for current protection, communications, and language. The standard package still includes critical current protections like transformer differential, ground/neutral/phase/negative time overcurrent, ground/neutral/phase/negative instantaneous overcurrent, and many more. The communications package includes a front USB, a rear RS485 port with Modbus RTU, and support for DNP3.0 and IEC61870-5-103. This model is programmed in English and does not have programmable LEDs.

Environmental Features

The 345-EP1G1HESNNSNDN does not have harsh environment conformal coating, so this unit is best suited for less hazardous areas of a utility or industrial environment. This unit does have the highly convenient drawout case design, though, which streamlines testing and maintenance and reduces downtime in your system. This unit operates on a high-voltage 110-230VAC/110-250VDC power supply.
