LITTELFUSE 3.15A Slow-Blow Cartridge Fuse, 5mm x 20mm, 250V AC

The LITTELFUSE 3.15A Slow-Blow Cartridge Fuse is an essential protection component from the renowned Slo-Blo 239 Series. Engineered for reliability, this fuse is designed to safeguard sensitive electrical circuits by interrupting excessive current flows, thereby preventing damage to equipment and mitigating fire risks.

Featuring a slow-blow (time-delay) characteristic, it can tolerate harmless, temporary current surges—such as those caused by motor start-ups or capacitive inrush currents—without rupturing. This makes it ideal for circuits with inductive loads. It will only blow under sustained overload conditions, providing stable and predictable protection.

Rated for 250 Volts AC and a nominal current of 3.15 Amperes, this fuse boasts a high breaking capacity of 100A AC, ensuring it can safely interrupt significant fault currents. Its compact, industry-standard 5mm x 20mm cartridge size (equivalent to 0.2” x 0.79”) allows for easy replacement and compatibility with a wide range of fuse holders and panels.

Constructed to meet rigorous safety standards, this fuse is a critical part of any maintenance toolkit for electrical systems, industrial machinery, consumer appliances, and power supplies. Its precise calibration ensures consistent performance, offering peace of mind and enhanced circuit integrity.
