It provides overcurrent and short-circuit protection in commercial and industrial power distribution systems. The JD6 frame is a well-established platform used in panelboards, switchboards, and motor control applications where high-ampacity branch and feeder circuit protection is required. Licensed electricians and electrical contractors are the primary installers of this device. Its 3-pole configuration makes it suited for three-phase distribution systems operating at up to 600 volts AC.\u003c\/p\u003e\n\u003cp\u003eThis breaker is used in commercial and industrial electrical distribution applications requiring 350-amp feeder or branch circuit protection. Typical installations include main distribution panels, sub-panels, motor control centers, and industrial switchboards operating on three-phase 600-volt systems. It is appropriate for new construction wiring as well as retrofit or replacement applications where an existing JD6-frame breaker requires substitution.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-pole configuration for three-phase circuit protection up to 600 volts\u003c\/li\u003e\n  \u003cli\u003e350-amp continuous current rating for high-ampacity feeder and branch circuits\u003c\/li\u003e\n  \u003cli\u003eJD6 frame class for compatibility with JD6-rated panelboards and switchboards\u003c\/li\u003e\n  \u003cli\u003eMolded case construction provides thermal-magnetic overcurrent and short-circuit protection\u003c\/li\u003e\n  \u003cli\u003eDesigned for commercial and industrial power distribution environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation circuit breaker for JD6-frame commercial and industrial panelboards and switchboards rated for 3-pole 600-volt applications.

De-energize and lock out the panel or switchboard before installing or replacing this breaker, following proper lockout\/tagout (LOTO) procedures. Verify that the bus rating, frame size, and interrupt capacity of the enclosure are compatible with this breaker before installation. Do not install this breaker in enclosures rated below the breaker voltage or amperage specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmpere Rating\u003c\/strong\u003e: 350 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Class\u003c\/strong\u003e: JD6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 18.301 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78364321308\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: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JXD63B350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383852007730,"sku":"JXD63B350","price":11980.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677909.jpg?v=1782609475","url":"https:\/\/voomisupply.com\/products\/siemens-jxd63b350-circuit-breaker-3-pole-600v-350a","provider":"Voomi Supply","version":"1.0","type":"link"}
