Fast acting fuse is an overcurrent protection device with extremely fast breaking speed, and its response time is much shorter than ordinary fuses. It is specially used to protect precision power electronic equipment such as semiconductor devices, inverters, frequency converters and power modules, avoiding equipment burnout due to short circuit and instantaneous overcurrent. It is the core protection accessory in the fields of new energy, industrial power and electronic equipment.
Its core performance advantage is fast breaking speed, cutting off fault current within milliseconds, and has accurate overload protection threshold, no false blowing due to slight current fluctuation. The rated current covers 1A-1000A, rated voltage up to 1500V, divided into DC and AC types. DC fast acting fuses are optimized for semiconductor circuits of new energy and energy storage, with excellent arc extinguishing performance.
Fast acting fuses are mainly used in semiconductor modules, photovoltaic inverters, energy storage converters, motor controllers and other scenarios, and need to be selected according to the equipment’s rated current, voltage and circuit type. Essfuse fast acting fuses are made of high-quality melt material, stable performance and reliable breaking, providing efficient and fast protection for precision semiconductor equipment.
