Operating on a universal auxiliary power supply (70-265 VAC \/ 88-300 VDC), the unit processes 5 A Phase CT and 5 A Ground CT signals to drive ANSI 50\/51 and 50N\/51N overcurrent algorithms, breaker failure logic, and thermal overload tracking. Integrated communications execute Modbus RTU\/TCP, DNP3.0, and IEC 60870-5-103 protocols across optional Ethernet fiber physical layers to export waveform captures and transient event logs.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e350-E-P5-G5-H-E-E-N-N-SN-D-N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Multilin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e435 mm x 435 mm x 435 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e70-265 VAC \/ 88-300 VDC universal auxiliary input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Inputs\u003c\/td\u003e\n\u003ctd\u003e5 A Phase CTs, 5 A Ground CTs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Functions\u003c\/td\u003e\n\u003ctd\u003eANSI 50\/51, 50N\/51N, sensitive ground, breaker failure, thermal overload\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Outputs\u003c\/td\u003e\n\u003ctd\u003e2 electromechanical relays configurable for trip, alarm, or control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocols\u003c\/td\u003e\n\u003ctd\u003eModbus RTU \/ TCP\/IP, DNP3.0, IEC 60870-5-103, optional Ethernet fiber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTiming Range\u003c\/td\u003e\n\u003ctd\u003eNeutral overcurrent timing: 0.00 to 300.00 s in 0.01 s increments\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImmunity Ratings\u003c\/td\u003e\n\u003ctd\u003eEMC immunity certified per IEC 61000-4-8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eBackplane Bus Communication Velocity and Deterministic Networks\u003c\/h3\u003e\n\u003cp\u003eThe GE Multilin 350-E-P5-G5-H-E-E-N-N-SN-D-N maintains backplane bus communication velocity across EtherNet\/IP and Modbus TCP\/IP networks. Onboard digital signal processors sustain firmware flash compatibility during transient waveform logging to non-volatile memory. By isolating high-speed current calculation loops from external SCADA network requests, the relay hardware preserves deterministic execution during simultaneous trip relay output operations and automated breaker control sequences.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How are the output relays configured for fault isolation schemes?\u003c\/p\u003e\n\u003cp\u003eA: The module contains two electromechanical relays that field engineers program directly via front panel logic or SCADA interfaces to execute trip commands, system alarms, or breaker interlock controls.\u003c\/p\u003e\n\u003cp\u003eQ: What parameter steps are available for neutral overcurrent timing adjustments?\u003c\/p\u003e\n\u003cp\u003eA: The neutral overcurrent element allows timing settings from 0.00 to 300.00 seconds adjustable in precise 0.01-second steps.\u003c\/p\u003e\n\u003cp\u003eQ: How does the unit preserve transient logs during system power losses?\u003c\/p\u003e\n\u003cp\u003eA: The internal transient recorder writes waveform captures and event logs directly to battery-backed RAM to preserve diagnostic data until power resumes.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eEngineers must observe strict field installation procedures during panel layout and connection:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMount the 435 mm x 435 mm x 435 mm chassis securely into the panel cutout, verifying drawout locking mechanisms seat flush against the rack frame.\u003c\/li\u003e\n\u003cli\u003eConnect the 70-265 VAC or 88-300 VDC power conductors to the designated power terminals using properly sized lug connectors.\u003c\/li\u003e\n\u003cli\u003ePass 5 A current transformer secondary wiring through shorting block terminals before connecting to Phase and Ground CT terminals.\u003c\/li\u003e\n\u003cli\u003eAttach a dedicated ground strap between the relay chassis grounding stud and the enclosure earth bus to ensure compliance with IEC 61000-4-8 EMC immunity criteria.\u003c\/li\u003e\n\u003cli\u003eRun Ethernet fiber cables and RS-485 communication lines through dedicated low-voltage cable paths separated from AC power lines.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":43871054332003,"sku":"350-E-P5-G5-H-E-E-N-N-SN-D-N","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/191.1_434047de-5e15-4048-b67c-d9a5e181068e.jpg?v=1764832894","url":"https:\/\/www.autocontrolglobal.com\/products\/350-e-p5-g5-h-e-e-n-n-sn-d-n-ge-multilin-feeder-protection-relay","provider":"AutoControl Global","version":"1.0","type":"link"}
