About the 350-E-P5-G5-H-E-E-N-N-1E-D-N

Feeder Protection System 350-E-P5-G5-H-E-E-N-N-1E-D-N is a model three-phase current input that operates on five milliamperes, the ground currents will also operate on the same. It is important to note that the phase and ground currents must match and cannot be mixed, for example, you cannot have a P1 and G5 rating, different ratings of these input types can cause a mass of issues. The associated communication type, denoted by the 1E code, is a standard communication type, which is typically denoted by SN, with Ethernet, DNP3.0, IEC60870-5-104, and Modbus TCP/IP protocols as well. 

One key feature of this protection system is that it has a large number of programmable setpoints which makes this relay exceptionally flexible. The setpoints available with the 350-E-P5-G5-H-E-E-N-N-1E-D-N relay are grouped into several different groups and subgroups in the 350 Feeder Protection System Instruction Guide in chapter six. Some of the different setpoints are inputs and outputs, with output relays, virtual inputs, and contact inputs in this category; the system setup with flex curves A and B, user curve, power systems, and current and voltage sensing; and protection setpoints with two setpoint groups and a VT fuse failure. The setpoint groups for the protection setpoint are all labeled on page two of chapter six. 

All of the above features are what make purchasing the 350-E-P5-G5-H-E-E-N-N-1E-D-N wonderful, but another key feature of this relay is that it has a withdrawable small footprint which can save on not only space but rewiring as well. It also has a CPU that can control the relay functions by two different processors, both are Freescale thirty-two-bit microprocessors.
