Sinofuse RS306-1-Q5Z is an AC1250V fuse series covering nine verified rated-current models from 160A to 550A. 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.
RS306-1-Q5Z Series Overview
The 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.

RS306-1-Q5Z Model Selection
The RS306-1-Q5Z series provides nine verified current options from 160A through 550A. Select the required rated current first, then compare pre-arcing I²t, total I²t, and power loss at 0.5In and In where these characteristics are relevant to the equipment design. Confirm the complete MPN, AC1250V requirement, size code, and circuit requirements before replacement or procurement.
