All included variants use the 2H size code and share an M8 mounting-bolt configuration with a recommended installation torque of 11 N·m. The individual models differ by rated current, pre-arcing I²t, total I²t, and power loss. This page organizes those manufacturer-specified values into a single procurement-ready matrix so technical buyers can identify the exact model required and compare the electrical characteristics that change across the series.\u003c\/p\u003e\n\n\u003ch2\u003eRS308-HB-2H Series Overview\u003c\/h2\u003e\n\u003cp\u003eThe RS308-HB-2H group is part of the SINOFUSE RS308-HB 750VDC high-speed fuse family. The included models maintain the same 750VDC rating, 2H size designation, mounting hardware, and recommended mounting torque while providing seven rated-current selections. This makes rated current the primary Shopify selection attribute, with I²t and power-loss values available for model-by-model technical comparison.\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;\"\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;\"\u003e750 VDC\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;\"\u003eIncluded Rated 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;\"\u003e50–200 A\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;\"\u003e2H\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;\"\u003eMounting Bolt\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eM8\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;\"\u003eRecommended Mounting Torque\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e11 N·m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical data reference:\u003c\/strong\u003e SINOFUSE RS308-HB 750VDC Cylindrical Bolt-Connected High-Speed Fuse Selection Specification.\u003c\/p\u003e\n\n\u003ch2\u003eRS308-HB-2H Model Selection\u003c\/h2\u003e\n\u003cp\u003eThe verified RS308-HB-2H selection covers 50A, 63A, 80A, 100A, 125A, 160A, and 200A ratings.
