2008 Littelfuse Automotive Circuit Protection Products
MEGA Fuse Rated 32V
The MEGA Fuse is designed for high current circuit protection
up to 500A with “Diffusion Pill Technology.” The MEGA Fuse
also provides time delay characteristics. Designed and patented
by Littelfuse, the MEGA Fuse is ideal for battery and alternator
protection application and other heavy gauge cables requiring
ultra-high current protection.
Die von Littelfuse entwickelte und patentierte MEGA-Sicherung
in Diffusionspillen-Technologie mit trger Charakteristik
ist für berstrom-Schutzlsungen von bis zu 500A
konzipiert. Sie eignet sich ideal für Batterie- und Generator-
Schutzanwendungen oder andere Bereiche mit sehr groen
Kabelquerschnitten, die extrem hohe Anforderungen an den
berstromschutz stellen.
