70V High Performance (HP) Fuse is designed for high current circuit protection
up to 500A with “Diffusion Pill Technology.” The MEGA 70V HP features 1MOhm Open State
Resistance after fuse opening to guarantee safe interruption at any voltage up to 70V. The
MEGA
®
70V HP Fuse is ideal for battery and alternator protection application and other heavy
gauge cables requiring ultra-high current protection.
