It is a 3-pole unit rated at 600 volts, providing the overcurrent sensing and tripping mechanism that protects electrical circuits from sustained overloads and short-circuit faults. This trip unit is installed inside the breaker frame and is a field-replaceable component, allowing technicians to restore breaker functionality without replacing the entire assembly. Licensed electricians and industrial maintenance technicians are the primary installers of this type of component in commercial and industrial distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis trip unit is intended for use in commercial and industrial electrical distribution applications where JD6 frame circuit breakers are deployed. Typical installation scenarios include motor control centers, switchboards, panelboards, and distribution panels operating at up to 600 volts. It is suited for environments requiring reliable overcurrent protection across all three phases of a power distribution circuit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-pole configuration for three-phase overcurrent protection\u003c\/li\u003e\n  \u003cli\u003e600-volt rating suitable for commercial and industrial distribution systems\u003c\/li\u003e\n  \u003cli\u003eField-replaceable design allows restoration of breaker function without full assembly replacement\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with JD6 frame molded-case circuit breakers\u003c\/li\u003e\n  \u003cli\u003eProvides overload and short-circuit trip sensing for downstream circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement trip unit for SIEMENS JD6 frame molded-case circuit breakers operating at 3-pole, 600-volt configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified, licensed electrician in accordance with NFPA 70 (NEC) requirements and all applicable local codes. Always de-energize and lock out the circuit breaker and upstream power source before beginning any service work on the trip unit or breaker assembly. Confirm the replacement trip unit rating matches the original equipment specifications before installation. Do not attempt to modify or adjust the trip mechanism beyond manufacturer-specified procedures.\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\u003eFrame Compatibility\u003c\/strong\u003e: JD6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78364321347\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: JD63T300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383539499314,"sku":"JD63T300","price":6597.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677942.jpg?v=1782599879","url":"https:\/\/voomisupply.com\/products\/siemens-jd63t300-trip-unit-3-pole-600v-jd6-frame","provider":"Voomi Supply","version":"1.0","type":"link"}
