MEGA® 70V-SF51 High Performance (HP) Fuses

Littelfuse MEGA® 70V-SF51 High Performance (HP) Fuses are designed for high current circuit protection up to 500A with Diffusion Pill Technology, which is a mixing of molecules, atoms, or crystals in the solid, liquid, or gaseous state. The series provides 1MΩ open-state resistance after fuse opening, which guarantees safe interruption at any voltage up to 70V. These fuses are available in current ratings from 60A to 500A with an operating temperature range of -40°C to +125°C. Littelfuse MEGA 70V-SF51 HP Fuses are ideal for battery and alternator protection applications and other heavy gauge cables requiring ultra-high current protection.
