Product Specification

Fast Acting 5x20mm Ceramic Tube Fuse 300V AC DC 200mA-20A for Battery Energy Storage Systems

 
This series of fast-acting 5×20mm ceramic tube fuses is specifically designed to deliver precise, high-speed overcurrent protection for battery energy storage systems (BESS) and related DC power applications. Engineered with a quick-blow characteristic, these fuses respond instantaneously to short-circuit faults and severe overloads, effectively limiting fault current and minimizing energy let-through to protect sensitive battery cells, power conversion electronics, and balance-of-plant components. With a versatile current range from 200mA to 20A and dual AC/DC voltage rating of 300V, these compact fuses offer an ideal balance of size, performance, and reliability for modern energy storage applications.
