High Current Fuses
MEGA
®
High Performance Fuse Rated 70V-SF56
The MEGA
®
70V-SF56 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. The bigger pitch of 56mm serves as a
mechanical coding feature to avoid standard SF51 fuses being mounted.
Littelfuse products are not designed for, and shall not be used for, any purpose (including, without limitation, automotive, military, aerospace, medical, life-saving, life-sustaining or nuclear facility applications, devices intended for
