Siemens HRD63B180 is an 1800A, 3-pole SENTRON molded case circuit breaker built around the RD frame and a thermal-magnetic trip unit. For compatible existing and legacy equipment that calls for this configuration, the HRD63B180 provides a clearly defined form, fit, and function replacement option. It's built to last, but proper installation starts with confirming every critical specification against the equipment being serviced.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1800A, 3-pole configuration: Gives you two of the first specifications to compare with the existing breaker and equipment documentation.\u003c\/li\u003e\n\u003cli\u003eRD frame: An important detail when checking physical and equipment compatibility—not just electrical ratings.\u003c\/li\u003e\n\u003cli\u003e600V rating: Matches systems that specifically require this voltage rating, along with the breaker's other specifications.\u003c\/li\u003e\n\u003cli\u003eThermal-magnetic trip unit: Uses the trip configuration identified by the manufacturer for the HRD63B180.\u003c\/li\u003e\n\u003cli\u003eLugs included on both sides: The breaker has TC5R600 line- and load-side lugs.\u003c\/li\u003e\n\u003cli\u003eDefined conductor range: Lugs accept 300–600 kcmil copper conductors only, reducing guesswork in connection matching.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siemens\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number \/ MFN:\u003c\/strong\u003e HRD63B180\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArticle Number:\u003c\/strong\u003e US2:HRD63B180\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e SENTRON\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Family:\u003c\/strong\u003e HRD6, 50 kAIC, 600 VAC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaker Type:\u003c\/strong\u003e Molded Case Circuit Breaker\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame:\u003c\/strong\u003e RD\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e 1800 A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 600 V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating at 600 V:\u003c\/strong\u003e 50 kAIC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupt Rating at 480 V:\u003c\/strong\u003e 65 kAIC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Unit:\u003c\/strong\u003e Thermal-Magnetic\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Designation:\u003c\/strong\u003e Standard 40°C breaker\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine-Side Lugs:\u003c\/strong\u003e TC5R600\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad-Side Lugs:\u003c\/strong\u003e TC5R600\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Range:\u003c\/strong\u003e 300–600 kcmil\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material:\u003c\/strong\u003e Copper only\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9\" W x 16\" H x 6.19\" D\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Weight:\u003c\/strong\u003e 169.403 lb\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards:\u003c\/strong\u003e UL 489 \/ IEC 60947-2\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 783643008946\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Mexico\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDangerous Goods:\u003c\/strong\u003e No\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial Compliance and Certifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor the HRD63B180, Siemens specifically states that the breaker meets UL 489 and IEC 60947-2 standards.
