Dual-break rotating contacts limit peak let-through current during a short circuit, and the 80%-rated B-Frame body packs full capacity into roughly two-thirds the footprint of legacy Square D F-Frame breakers — so it drops straight into existing I-Line mounting space during retrofits and panel expansions. It is the designated replacement for the discontinued FH36070. Line side uses I-Line jaws with ABC phase sequence; load side ships with mechanical lugs and a push-to-trip test button.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSquare D \/ Schneider Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSeries\u003c\/th\u003e\n\u003ctd\u003ePowerPacT B-Frame, I-Line, Type BJ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eBJA36070\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAmperage\u003c\/th\u003e\n\u003ctd\u003e70A (125A frame)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e600Y\/347VAC, 480VAC, 480Y\/277VAC, 240VAC, 208Y\/120VAC, 250VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePoles\u003c\/th\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePhase\u003c\/th\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAIC Rating\u003c\/th\u003e\n\u003ctd\u003e100kA @ 208Y\/120VAC, 100kA @ 240VAC, 65kA @ 480VAC and 480Y\/277VAC, 25kA @ 600Y\/347VAC, 50kA @ 250VDC (UL 489)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMounting Style\u003c\/th\u003e\n\u003ctd\u003eI-Line Plug-In\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTerminal Type\u003c\/th\u003e\n\u003ctd\u003eI-Line jaws on line side, mechanical lugs on load side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePhase Sequence\u003c\/th\u003e\n\u003ctd\u003eABC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eContinuous Current Rating\u003c\/th\u003e\n\u003ctd\u003e80%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eFor Use With\u003c\/th\u003e\n\u003ctd\u003eSquare D I-Line Panelboards, Switchboards, and Busway Plug-In Units\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTrip Technology\u003c\/th\u003e\n\u003ctd\u003eThermal Magnetic (LI — Long-Time, Instantaneous)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTrip Adjustability\u003c\/th\u003e\n\u003ctd\u003eFixed Thermal \/ Fixed Magnetic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWire Range\u003c\/th\u003e\n\u003ctd\u003e#14 AWG – 2\/0 AWG (Al\/Cu)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eReplaces\u003c\/th\u003e\n\u003ctd\u003eSquare D FH36070 and legacy F-Frame I-Line breakers, per Schneider F-Frame to B-Frame conversion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAvailable Options\u003c\/th\u003e\n\u003ctd\u003eShunt Trip, Auxiliary Switch, Undervoltage Release, Alarm Switch, Padlock Attachment, Rotary Handle, Terminal Shields\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eStandards\u003c\/th\u003e\n\u003ctd\u003eUL 489, CSA C22.2 No. 5, IEC 60947-2, IEC 60947-5-1, NEMA AB 1, NMX J-266, GB 14048.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eApprovals\u003c\/th\u003e\n\u003ctd\u003eUL, CSA, CE, CCC, EAC, IEC, NOM, UKCA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eOperating Temperature\u003c\/th\u003e\n\u003ctd\u003e-25°C to 70°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShipping Dimensions\u003c\/th\u003e\n\u003ctd\u003e14 x 10 x 10 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShipping Weight\u003c\/th\u003e\n\u003ctd\u003e8 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the interrupting rating of the BJA36070?\u003c\/h3\u003e\n\u003cp\u003e65kA at 480VAC, 100kA at 240VAC, 25kA at 600Y\/347VAC, and 50kA at 250VDC.
