The series is rated DC500V, uses the EV protection category, and provides a DC breaking capacity of 20kA with a 2 ±0.5ms time constant. All included models share the L-3EC mechanical construction with M6 lower-bolt mounting, while rated current, pre-arcing I²t, clearing I²t, power loss and identification color vary by model. This page consolidates the exact purchasable MPNs and manufacturer-published electrical characteristics for vehicle electrical-system selection, replacement review and B2B procurement.\u003c\/p\u003e\n\n\u003ch2\u003eEV315-L-3EC Series Overview\u003c\/h2\u003e\n\u003cp\u003eThe EV315-L-3EC family includes 10A, 15A, 20A, 30A, 40A and 50A variants. SINOFUSE specifies conformity to ISO 8820, JASO D622 and GB\/T 31465 and identifies the series as RoHS compliant. The L-3EC construction uses lower M6 bolt connections with a recommended installation torque of 6 ±1 N·m. Published unit weight is 14.8 ±1.5g. Manufacturer I²t data is obtained under a DC520V, 20.6kA test condition with L\/R = 2.63ms, and the published time-current data specifies a minimum breaking current of at least 2 × In.\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;\"\u003eLower bolt-on road vehicle 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;\"\u003eDC500V\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;\"\u003e10A–50A\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;\"\u003eProtection Category\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eEV\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;\"\u003eDC 20kA, time constant 2 ±0.5ms\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;\"\u003eMinimum Breaking Current\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eAt least 2 × In\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\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eLower bolt, M6\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 Torque\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e6 ±1 N·m\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;\"\u003eStandards\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003eISO 8820, JASO D622, GB\/T 31465\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;\"\u003eNormal Ambient Temperature\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0;\"\u003e-5°C to 40°C\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 EV315-H-3EB\/L-3EC\/3EN\/3EC\/3EF Road Vehicle Fuse Specification, document ZR\/YC-0155 B1.\u003c\/p\u003e\n\n\u003ch2\u003eEV315-L-3EC Model Selection\u003c\/h2\u003e\n\u003cp\u003eThe EV315-L-3EC series provides six verified current options from 10A through 50A.
