This Square D breaker features a J-Frame construction and is built for unit mount applications with lugs for secure electrical connections. The breaker includes a push-to-trip mechanism for safe manual tripping without exposure to live parts, and its shorter handle design allows for panel doors to close properly. The LA36400MB is suitable for main panel use and offers robust protection for critical circuits. This molded case circuit breaker utilizes thermal (overload) and magnetic (short circuit) sensing elements in each pole for precise and dependable operation. The unit is designed for flexible mounting and termination options, making it adaptable to a variety of panel configurations. The breaker is certified to UL 489, CSA, and IEC standards, ensuring compliance with major safety and performance requirements. \u003cul\u003e \u003cli\u003ePart Number: LA36400MB\u003c\/li\u003e \u003cli\u003eManufacturer: Square D\u003c\/li\u003e \u003cli\u003eAmperage: 400A\u003c\/li\u003e \u003cli\u003eVoltage: 600V AC\u003c\/li\u003e \u003cli\u003ePoles: 3\u003c\/li\u003e \u003cli\u003eMounting Type: Unit Mount\u003c\/li\u003e \u003cli\u003eInterrupt Rating: 22kA @ 600V AC, 10kA @ 250V DC\u003c\/li\u003e \u003cli\u003eSeries\/Frame: J-Frame\u003c\/li\u003e \u003cli\u003eTechnology: Thermal Magnetic\u003c\/li\u003e \u003cli\u003eElectrical Connection: Lugs\u003c\/li\u003e \u003cli\u003eStandards: UL 489, CSA, IEC\u003c\/li\u003e \u003cli\u003ePush-to-Trip Feature\u003c\/li\u003e \u003c\/ul\u003e At \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: LA36400MB\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Square D\u003c\/li\u003e\n\u003cli\u003eCategory : Circuit Breaker\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Molded Case\u003c\/li\u003e\n\u003cli\u003eFamily : I-Line\u003c\/li\u003e\n\u003cli\u003eType : LA\u003c\/li\u003e\n\u003cli\u003eVoltage : 600\u003c\/li\u003e\n\u003cli\u003eAmperage : 400\u003c\/li\u003e\n\u003cli\u003ePhase : 3\u003c\/li\u003e\n\u003cli\u003ePoles : 3\u003c\/li\u003e\n\u003cli\u003eAIC rating : 30kA@480V\u003c\/li\u003e\n\u003cli\u003eConnection : I-Line Style Plug-In\u003c\/li\u003e\n\u003cli\u003eFunctions : LI - Long-Time and Instantaneous\u003c\/li\u003e\n\u003cli\u003eFrame Size : L Frame\u003c\/li\u003e\n\u003cli\u003eProtection : Thermal Magnetic\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWeight : 20 \u003c\/li\u003e\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Square D","offers":[{"title":"Re-Certified","offer_id":42915058483359,"sku":"LA36400MB-ReCert","price":1156.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/LA36400_0.jpg?v=1711793982","url":"https:\/\/essentialparts.com\/products\/la36400mb-square-d-400a-600v-3-pole-thermal-magnetic-molded-case-circuit-breaker","provider":"Essential Electric Supply","version":"1.0","type":"link"}
