The MIF II system utilizes selectable ANSI time-overcurrent (51\/51N) and instantaneous overcurrent (50\/50N) algorithms alongside thermal image protection. Real-time signal analysis across 5 A phase\/ground inputs maintains phase overcurrent coordination and ground fault sensitivity, preserving continuity for healthy distribution feeders while capturing oscillography and event records for post-fault diagnosis.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What control power range is supported by the \"HI\" power supply option?\u003c\/p\u003e\n\u003cp\u003eA: The high-voltage \"HI\" power supply unit operates across 110 to 250 VDC (88–300 VDC absolute range) or 110 to 230 VAC (88–264 VAC absolute range).\u003c\/p\u003e\n\u003cp\u003eQ: Does the MIFIIPA55E10HI00 support automatic reclosing?\u003c\/p\u003e\n\u003cp\u003eA: No. The \"0\" digit in the ordering code specifies the unit is supplied without internal auto-recloser functionality.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm control power source voltage matches the HI power supply limits (110–250 VDC or 110–230 VAC) prior to energizing the unit.\u003c\/li\u003e\n\u003cli\u003eVerify phase CT and ground CT secondary wires are shorted at the test block before disconnecting or installing relay current input terminals.\u003c\/li\u003e\n\u003cli\u003eMount the relay flush into the panel cutout, securing the retaining clamps to maintain tight panel seating.\u003c\/li\u003e\n\u003cli\u003eWire the rear RS485 communication port using shielded twisted-pair cable, terminating the shield ground strictly at the master SCADA panel.\u003c\/li\u003e\n\u003cli\u003eUpload existing configuration settings via EnerVista software or front RS232 port, verifying CT ratios and trip curves match system protection studies.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GE","offers":[{"title":"Default Title","offer_id":50206939480138,"sku":"MIFIIPA55E10HI00","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8569\/3770\/files\/F650BABF2G1HI_4_371dc903-6b56-4782-8fad-cc71cabe97bd.png?v=1790067431","url":"https:\/\/www.topbrandsplc.com\/products\/ge-multilin-mifiipa55e10hi00-mifii-digital-feeder-relay","provider":"Topbrands PLC Limited","version":"1.0","type":"link"}
