Current-limiting construction reduces peak let-through energy during a short circuit, protecting downstream conductors and gear. The H-Frame occupies the same I-Line mounting space as Square D's discontinued F-Frame breakers, making it a straight plug-on replacement for the FC36080 and FH36080. A Visi-Trip indicator flags a fault trip on sight, and the ABC phase-sequence jaws seat directly onto the panelboard bus.\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 H-Frame, I-Line, Type HJ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eHJA36080\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAmperage\u003c\/th\u003e\n\u003ctd\u003e80A (150A frame)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e600VAC, 480VAC, 240VAC, 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 @ 240VAC, 65kA @ 480VAC, 25kA @ 600VAC, 20kA @ 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 and Switchboards\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 – 3\/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 FC36080, FH36080\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, Motor Operator, Rotary Handle\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, NEMA AB 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eApprovals\u003c\/th\u003e\n\u003ctd\u003eUL, CSA, CE, IEC, NOM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eConstruction Features\u003c\/th\u003e\n\u003ctd\u003eCurrent Limiting, HACR Rated, Visi-Trip Indicator\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 HJA36080?\u003c\/h3\u003e\n\u003cp\u003e65kA at 480VAC, 100kA at 240VAC, 25kA at 600VAC, and 20kA at 250VDC.\u003c\/p\u003e\n\u003ch3\u003eWhat does HJA36080 stand for?\u003c\/h3\u003e\n\u003cp\u003eH = PowerPacT H-Frame, J = 65kA interrupting rating at 480VAC, A = I-Line plug-in with ABC phase sequence, 3 = 3 poles, 6 = 600V class, and 080 = 80 amps.\u003c\/p\u003e\n\u003ch3\u003eWhich older Square D breakers does the HJA36080 replace?\u003c\/h3\u003e\n\u003cp\u003eIt replaces the discontinued FC36080 and FH36080.
