About the 350-E-P5-G5-H-E-S-N-M-SN-D-N
High Voltage model 350-E-P5-G5-H-E-S-N-M-SN-D-N is a drawout protection relay and only has a standard communication type, with ports both in the front and back. The port on the front of the model is labeled as a USB port with the port on the rear of the device is labeled as an RS485 port with Modbus RTU, IEC60870-5-103, and DNP3.0 protocols.
This relay and its small withdrawable option make it best to be used for panel mounting with retrofit or newer installations. The hardware on the 350-E-P5-G5-H-E-S-N-M-SN-D-N relay helps with not only control features but protection features as well which makes this relay specifically ideal for use with total feeder control and protection. This model also features frequency measurement which will measure between the zero crossings of the Bus VT phase A voltage on the 350-E-P5-G5-H-E-S-N-M-SN-D-N relay. The resulting signals will be passed through a lower pass filter to stave off potential inaccurate zero crossings.
When looking at the entire order code of this model it is important to note every character as every character will indicate a different function, some of the functions associated with this model are the power supply, current protection, case design, phase currents, and more. As mentioned prior this model has a high-voltage power supply but the specific power supply is either one hundred and ten to two hundred and thirty volts of alternating current or one hundred and ten to two hundred and fifty volts of direct current. It is important to note that there is an L character associated with the power supply function which is denoted as the language but can only be used with drawout case designs.
