Its construction incorporates a non-interchangeable thermal-magnetic trip unit that provides long-time overload and instantaneous short-circuit protection without requiring an external electronic trip device. The breaker supports three-phase circuits, uses bolt-on mounting, and is rated for 600 volts alternating current or 500 volts direct current, with interrupting capacities of 35 kiloamperes at 600 volts alternating current and 65 kiloamperes at 480 volts alternating current. Siemens specifies the HJXD63B300 as a standard 40 degrees Celsius breaker with high breaking capacity, and the standard configuration is supplied without line or load lugs installed. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e300-Ampere Rating: Provides a continuous current rating of 300 amperes for industrial and commercial distribution circuits. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eThree-Pole Configuration: Uses three poles for simultaneous protection and isolation of three-phase electrical circuits. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e600-Volt Capability: Rated for operation up to 600 volts alternating current and 500 volts direct current. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eThermal-Magnetic Protection: Uses a non-interchangeable thermal-magnetic trip mechanism for overload and short-circuit protection. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh Interrupting Capacity: Provides 35 kiloamperes interrupting capacity at 600 volts and 65 kiloamperes at 480 volts alternating current. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eJD Frame Construction: Built on the Siemens JD frame and classified as a Type HJXD6 high-interrupting-capacity breaker. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eBolt-On Mounting: Designed for bolted installation within compatible Siemens electrical distribution equipment. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eStandards Compliance: Meets UL 489 and IEC 60947-2 requirements specified by Siemens for this circuit breaker. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe HJXD63B300 delivers the reliability and precision required for overload protection, short-circuit interruption, and three-phase circuit isolation in industrial electrical distribution systems.\u003c\/p\u003e\n\u003cp id=\"p-rc_c7b8f4fae39e183e-25\"\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":52614434128170,"sku":"HJXD63B300","price":1865.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1600_89df3ce8-ee03-4a81-8afd-1170005d8d88.webp?v=1789504227","url":"https:\/\/iqelectro.com\/products\/siemens-hjxd63b300-sentron-300-ampere-three-pole-600-volt-molded-case-circuit-breaker","provider":"IQElectro","version":"1.0","type":"link"}
