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 träger Charakteristik
ist für Überstrom-Schutzlösungen von bis zu 500A
konzipiert. Sie eignet sich ideal für Batterie- und Generator-
Schutzanwendungen oder andere Bereiche mit sehr großen
Kabelquerschnitten, die extrem hohe Anforderungen an den
Überstromschutz stellen.
