Littelfuse 215 Series Time Delay Ceramic Cartridge Fuse - 5A

The Littelfuse 215 Series is a range of high-quality ceramic cartridge fuses designed for supplementary protection in a wide variety of electrical and electronic equipment. These time-delay (slow-blow) fuses are engineered to provide reliable protection for components and internal circuits, withstanding temporary inrush currents that would cause a standard fuse to fail unnecessarily.

Constructed with a robust ceramic body, these fuses feature tin-plated copper leads and nickel-plated brass end caps for excellent conductivity and corrosion resistance. They are manufactured to meet stringent IEC 60127-2, sheet 5 specifications, ensuring international compatibility and reliability for global applications. A key feature is their remarkable interrupting capacity, safely breaking fault currents up to 1.5kA.

The time-delay characteristic makes these fuses ideal for protecting circuits with motors, transformers, solenoids, or capacitive loads where a momentary high current is normal during start-up. They help prevent nuisance blowing while still providing critical protection against sustained overloads and short circuits.
