The manufacturer presents these models as bolted-connection, partial-range protection fuses with a shared 1000 VDC voltage rating, aR utilization category, size code 01, and breaking capacities of 50 kA at L\/R=10 ms and 150 kA at L\/R=5 ms. Variant-level differences include rated current, pre-arcing I²t, fusing I²t, and power loss. This page consolidates the verified models into one selection matrix so procurement teams can compare ratings, identify the required variant, and submit a precise B2B RFQ.\u003c\/p\u003e\n\n\u003ch2\u003eRSZ307-01-T5Z Series Overview\u003c\/h2\u003e\n\u003cp\u003eThe RSZ307-01-T5Z family uses a common bolted-connection construction and size 01 mechanical format across the listed current ratings. The manufacturer specifies a common product weight of 340 g with a ±5% tolerance. The supplied technical drawing presents the fuse outline and mounting dimensions in millimeters for mechanical-fit review. Packaging information on the manufacturer sheet specifies a minimum package quantity of 1 piece per box and a carton quantity of 30 pieces. Electrical protection characteristics and model-specific energy values should be checked against the requirements of the protected circuit before ordering or replacing an installed fuse.\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 Value\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;\"\u003eBolted-connection partial-range high-speed fuse\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;\"\u003eDC 1000 V\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;\"\u003e125–400 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;\"\u003eUtilization Category\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eaR\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;\"\u003eBreaking Capacity\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e50 kA at L\/R=10 ms; 150 kA at L\/R=5 ms\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;\"\u003eConnection\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eBolted connection\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;\"\u003e01\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;\"\u003eProduct Weight\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e340 g ±5%\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;\"\u003eRoHS\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eCompliant\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 “RSZ307-01-T5Z 1000V Series High-Speed Fuse” datasheet.\u003c\/p\u003e\n\n\u003ch2\u003eRSZ307-01-T5Z Model Selection\u003c\/h2\u003e\n\u003cp\u003eThe series provides seven verified rated-current options from 125 A to 400 A.
