Energy Storage Fuses 1000V/1500V DC | Essfuse
Energy storage fuses are the core protective components of battery energy storage systems (ESS), which bear the important responsibility of overcurrent and short-circuit protection for high-voltage DC circuits. Different from ordinary fuses, energy storage fuses need to adapt to the complex working conditions of rapid current fluctuation, wide temperature change and long-term outdoor operation of energy storage systems, and have higher requirements for breaking capacity, insulation performance and service life.
Essfuse focuses on the R&D and production of energy storage fuses, launching 1000V DC and 1500V DC two mainstream voltage specifications, with a current range covering 10A-125A, and a breaking capacity up to 20kA-50kA. Our energy storage fuses adopt silver-nickel alloy melt, high-temperature resistant ceramic tube and epoxy sealing structure, which can operate stably in the environment of -40℃ to 85℃, and effectively avoid the safety risks caused by battery thermal runaway, line damage and inverter failure.
All Essfuse energy storage fuses comply with IEC 60269-1, IEC 60269-6 and UL 248-13 international standards, and have passed strict electrical and mechanical performance tests, which are widely used in industrial energy storage stations, user-side energy storage cabinets, microgrid systems and large-scale new energy power stations. When selecting energy storage fuses, it is necessary to match the system voltage, operating current and installation environment to ensure the safe and stable operation of the entire energy storage system.
