Solar fuse is a special protection device for outdoor solar power systems, covering photovoltaic power stations, solar street lights, solar charging piles and other scenarios. It has interoperable performance with PV fuses, and focuses more on outdoor weather resistance optimization, with the characteristics of UV
PV fuse is a special protection device for solar photovoltaic power generation systems, mainly used for circuit protection of photovoltaic modules, photovoltaic combiner boxes and inverters. It is suitable for DC high voltage circuits of photovoltaic systems, with the characteristics of DC arc extinguishing, strong
1500V DC fuses have higher insulation, better arc extinction, wider temperature range, and stronger breaking capacity than 1000V DC fuses. Essfuse uses ceramic tubes, silver alloy melts, epoxy sealing, and optimized arc chambers. It works stably from -40℃ to 85℃.
The biggest difference between DC fuses and AC fuses is arc extinction. AC has a zero-crossing point, so the arc is easy to extinguish. DC has no zero point, so the arc is harder to extinguish. Therefore, DC fuses need a special arc-extinguishing structure. DC
Thermal runaway is the main safety risk in lithium batteries. Fast-acting fuses with low I²t can cut off fault current within milliseconds, preventing thermal runaway from spreading. Fuses are installed in battery modules, BMS, and battery clusters. They protect the whole system from fire and
Energy storage fuse is a special protection device for energy storage power stations, household energy storage and industrial and commercial energy storage systems. It is specially designed for energy storage battery packs, energy storage converters (PCS) and high voltage DC Fuse circuits, with the characteristics
Semiconductor fuse is a precision protection device specially designed for semiconductor power devices, with the characteristics of low power consumption, fast response and high precision. It is suitable for IGBT, MOS tube, rectifier bridge and other semiconductor components, solving the problem that semiconductor devices have
Correct installation of PV fuses directly affects safety and lifespan. PV fuses are mainly installed in combiner boxes and string circuits. You must fix the fuse holder firmly, connect wires tightly, maintain correct polarity, and apply waterproof insulation outdoors. Loose connections cause overheating and burnout.
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
Automotive fuse is the “security guard” of vehicle circuit, specially used to protect vehicle circuit equipment. When the circuit has overcurrent or short circuit fault, the fuse will automatically blow to cut off the circuit, avoiding the burning of lights, batteries, central control, motors and
