MEGA Fuse (60–400A)

Protect your high-current DC wiring with a MEGA fuse sized to match your system's load. Available from 60 to 400 Amps, these fuses fit any standard MEGA fuse holder and are a must-have for solar, RV, and marine power setups.

Choosing the right amp rating: select a fuse rated slightly above your circuit's maximum current, but below your wire's maximum rating. For example, if your system moves 120A at peak power, use a 125A fuse with wire rated for at least 130A — that way everything operates normally, but the fuse blows before your equipment or wiring is damaged in a short circuit.

Pick your amp rating above. Stocked ratings: 60, 80, 100, 125, 150, 200, 250, 300 and 400 amps.
