All included variants use size code 1, while rated current, pre-arcing I²t, total I²t, and power-loss values differ by exact model. The series structure allows procurement engineers and technical buyers to compare the published electrical data for each complete MPN in one place. For sourcing or replacement review, select the required current rating first, then compare the corresponding I²t and power-loss values against the requirements of the protected circuit or equipment before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eRS306-1-Q5Z Series Overview\u003c\/h2\u003e\n\u003cp\u003eThe RS306-1-Q5Z family is organized around a common AC1250V rating and size code 1 construction. Nine exact models are verified within the supplied data, beginning at 160A and extending through 200A, 250A, 315A, 350A, 400A, 450A, 500A, and 550A. The electrical comparison data supplied for every model includes pre-arcing I²t, total I²t, power loss at 0.5In, and power loss at In. Keeping these model-specific values separate from the common series specifications helps buyers identify the required variant without treating one model's performance values as representative of the entire range.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 13px; margin-top: 16px; font-family: sans-serif;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 8px 10px; background-color: #f2f2f2; font-weight: bold; color: #333; text-align: left; vertical-align: top;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 8px 10px; background-color: #f2f2f2; font-weight: bold; color: #333; text-align: left; vertical-align: top;\"\u003eSeries Data\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eFuse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eRated Voltage\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eAC1250V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eRated Current Range\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e160A–550A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eSize Code\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eVerified Model Count\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eRS306-1-Q5Z Model Selection\u003c\/h2\u003e\n\u003cp\u003eThe RS306-1-Q5Z series provides nine verified current options from 160A through 550A.
