SCHURTER Glass Cartridge Fuse, Time Delay, 5 x 20mm, 250V - 6.3A

The SCHURTER FST Series Glass Cartridge Fuse is a high-quality, time-delay anti-surge non-resettable fuse designed to provide reliable overcurrent protection in a wide range of electrical and electronic applications. Featuring a robust glass tube construction with nickel-plated copper alloy endcaps, this miniature fuse ensures excellent conductivity and corrosion resistance for long-lasting performance.

Engineered with a Time-Lag T characteristic, this fuse is specifically designed to tolerate short-duration surge currents without breaking, making it ideal for circuits with high inrush currents. It functions as an IEC standard fuse, rigorously tested to meet international safety and performance benchmarks, including IEC 60127-2/3, UL248-14, and CSA C22.2 #248.14 standards.

With a compact form factor of 5mm x 20mm, this cartridge fuse is perfectly suited for space-constrained installations. It boasts a breaking capacity of 35A AC and operates reliably within an ambient air temperature range of -55°C to 125°C, ensuring stability even in demanding environments. Additional electrical specifications include a maximum voltage drop of 150mV and a maximum power dissipation of 1600mW.

Whether you are designing safety-critical equipment or maintaining existing electronic systems, the SCHURTER FST series fuse delivers the precision and dependability required for optimal circuit safety.
