Littelfuse Slo-Blo Cartridge Fuse, Slow Blow, 7A, 125V AC, 5mm x 20mm

The Littelfuse 239 Series Slo-Blo® Cartridge Fuse is a high-quality, slow-blow fuse designed for supplementary protection within appliances and utilisation equipment. Its primary function is to safeguard individual components and internal circuits from damage due to overcurrent conditions, ensuring the reliable operation of sensitive electronics. Manufactured to stringent UL, CSA, and ANCE 248 standards, it delivers dependable performance you can trust.

Featuring a glass body for visual inspection of the fuse element, this cartridge fuse is constructed with nickel-plated brass end caps and tin-plated copper leads, providing excellent conductivity and corrosion resistance. It is rated for 125V AC circuits with a high 10kA breaking capacity, capable of safely interrupting substantial fault currents. The 'slow blow' characteristic allows it to withstand brief, harmless current surges (such as those from motor start-up) without opening, while still providing protection against sustained overloads.

With a compact 5mm x 20mm metric size (0.2” x 0.79” imperial), it is suitable for a wide range of applications where space is limited. Its operational temperature range of -55°C to 125°C ensures stable performance in both extreme cold and high-heat environments, making it a versatile choice for various industrial and commercial settings.

This fuse is an essential component for designers and maintenance engineers seeking robust circuit protection that complies with international safety standards.
