General Electric Multilin 350-E-P0-G0-H-E-E-N-N-SN-N-N Protection Relay

About the 350-E-P0-G0-H-E-E-N-N-SN-N-N

The Feeder Protection System Relay 350-E-P0-G0-H-E-E-N-N-SN-N-N was produced by GE Multilin to operate as a relay model without any programmable light-emitting diodes (LEDs). The customary faceplate of this model has both inputs and outputs, there are ten inputs used with this model and there are seven outputs. The current protection used with this model has an extended configuration. 

According to the order code within one of the General Electric publications, the 350-E-P0-G0-H-E-E-N-N-SN-N-N model has standard communications features. The associated communications are a USB on the front of the device with an RS485 communication port on the backside. Please note that the RS4858 port is a Modbus RTU, with IEC60870-5-103, DNP3.0 standards. 

There are a wide variety of protection features available on the 350-E-P0-G0-H-E-E-N-N-SN-N-N relay device some of which are as follows: 

• Auxiliary Undervoltage designated by ANSI device 27X

• Phase Voltage designated by ANSI device 59P

• Cold Load Pickup designated by ANSI device CLP

• Neutral Directional Element designated by ANSI device 67N

• Negative Sequence Overvoltage designated by ANSI device 59_2

All of these features are just a few of the many protection features that are offered with this relay device. For more protection features refer to the GE Multilin 350 Instruction Manual which has not only extensive information on the protection features but information on the part breakdown and its codes available as well. 

There are two interfaces available with the 350-E-P0-G0-H-E-E-N-N-SN-N-N relay which are either interfacing through the EnerVista SR3 Setup Software or through the relay keypad and display. Chapter three of the GE Multilin 350 Instruction Manual will provide more extensive information about these two interfaces.
