It uses a thermal-magnetic trip mechanism to provide overload and short-circuit protection in three-phase electrical distribution systems. Wire range is 14 to 3\/0 AWG, accommodating a broad range of conductor sizes. Terminal connection options include I-Line and lug configurations. Licensed electricians install this breaker in panelboards, switchboards, and motor control centers where reliable branch-circuit protection is required under NEC guidelines.\u003c\/p\u003e\n\u003cp\u003eThis breaker is suited for commercial and industrial three-phase power distribution applications. The plug-in mounting style allows installation into compatible Square D panelboards and switchboards without additional hardware. The thermal-magnetic trip mechanism responds to both sustained overloads and instantaneous short-circuit events, making it appropriate for feeder and branch-circuit protection in demanding service environments. Multiple breaking capacity ratings extend its usefulness across a range of fault-current levels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45 amp continuous current rating at 600 VAC\u003c\/li\u003e\n  \u003cli\u003e3-pole configuration for three-phase circuit protection\u003c\/li\u003e\n  \u003cli\u003eThermal-magnetic trip mechanism for overload and short-circuit response\u003c\/li\u003e\n  \u003cli\u003eWire range of 14 to 3\/0 AWG supports varied conductor sizes\u003c\/li\u003e\n  \u003cli\u003eI-Line and lug terminal connection options\u003c\/li\u003e\n  \u003cli\u003ePlug-in mounting for tool-free installation into compatible panelboards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement molded case circuit breaker for use in compatible three-phase panelboards and switchboards accepting plug-in style breakers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panelboard or switchboard before handling or installing the breaker. Verify that the bus structure accepts the plug-in I-Line connection style and that conductor sizing falls within the 14 to 3\/0 AWG range before terminating wires. Do not exceed the breaker's voltage or amperage rating for the intended circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 45 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrip Mechanism\u003c\/strong\u003e: Thermal-Magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Range\u003c\/strong\u003e: 14 to 3\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Connection Type\u003c\/strong\u003e: I-Line and Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Plug In\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.86 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HDA36045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542142615858,"sku":"HDA36045","price":1029.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f405c5c465aa70951ec2bdcef2f97ed1_116beb48-2ef4-4b92-bc4a-bad0ee1f6bd8.jpg?v=1785893455","url":"https:\/\/voomisupply.com\/products\/square-d-hda36045-molded-case-circuit-breaker-45a-600v-3p","provider":"Voomi Supply","version":"1.0","type":"link"}
