Trip units control the overcurrent sensing and tripping functions of a molded-case circuit breaker, allowing field adjustment or replacement of the sensing mechanism without replacing the entire breaker assembly. This unit is rated for copper conductor applications and fits both 2-pole and 3-pole configurations. Licensed electricians and industrial maintenance technicians typically install or replace trip units during panel servicing, breaker retrofits, or when upgrading protection settings on existing switchgear.\u003c\/p\u003e\u003cp\u003eThis trip unit is suited for commercial and industrial electrical distribution systems where JD or LD frame Siemens molded-case circuit breakers are installed. It is commonly used in loadcenters, motor control centers, and panelboards requiring reliable overcurrent protection. The copper-rated design makes it appropriate for standard copper wiring installations in both new construction and retrofit applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompatible with JD and LD frame molded-case circuit breakers\u003c\/li\u003e\n\u003cli\u003eSupports 2-pole and 3-pole breaker configurations\u003c\/li\u003e\n\u003cli\u003eRated for copper conductor connections\u003c\/li\u003e\n\u003cli\u003eAllows trip unit replacement without full breaker changeout\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for standard panelboard and switchgear installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Siemens JD and LD frame molded-case circuit breakers in 2-pole and 3-pole configurations with copper conductors.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit breaker and all associated upstream equipment before beginning any work. Verify that the replacement trip unit matches the existing breaker frame designation and pole count before installation. Do not re-energize the panel until the trip unit is fully seated and secured per the manufacturer's instructions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Compatibility\u003c\/strong\u003e: JD and LD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePole Configuration\u003c\/strong\u003e: 2-pole and 3-pole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 8 inches x 5 inches x 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TC1J6600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383773135154,"sku":"TC1J6600","price":256.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678865.jpg?v=1782607016","url":"https:\/\/voomisupply.com\/products\/siemens-tc1j6600-circuit-breaker-trip-unit-jd-ld","provider":"Voomi Supply","version":"1.0","type":"link"}
