Product Description

Littelfuse 021612.5MXP is a fast acting 12.5A ceramic cartridge fuse designed to provide reliable overcurrent protection in electrical and electronic applications. Rated to operate at 250V AC, this fuse features a robust ceramic body that offers excellent thermal and mechanical durability.

The compact 5 x 20 mm size with an overall length of 20 mm and diameter of 5 mm fits industry-standard fuse holders, making it suitable for widespread usage in various industrial and commercial electrical systems. Its fast acting characteristic is ideal for protecting sensitive components such as semiconductors, including thyristors, diodes, and triacs, from short circuits and overload conditions.

The fuse operates reliably within a temperature range of -55°C to 125°C, ensuring stable performance even under challenging environmental conditions. It complies with major international certifications including SEMKO, CSA, CE, CCC, VDE, and UR, assuring safety and quality standards.

This type of ceramic fuse is preferred over glass fuses when higher capacity and greater mechanical strength are required. Its breaking capacity safely manages fault currents without damage or explosion. For circuits above 6.3A, the use of open-type fuse holders is recommended to reduce nuisance tripping near the rated current.

This fuse is extensively used for short-circuit protection of semiconductors like thyristors, diodes, and triacs in industrial automation and electrical equipment. Ceramic construction prevents overheating and extends fuse life compared to glass alternatives.

Ensures reliable operation and safety in HVAC, manufacturing, laboratory, and electrical automation environments. Ideal for protecting costly components and isolating fault conditions efficiently.
