MEGA Fuse Bundle

MEGA Fuse + Holder Bundle Kit (40A–300A UL-Listed Fuses, Single Holder)

Build your DC protection the clean, professional way — this bundle pairs our UL-listed MEGA fuses (choose 40A–300A) with a bolt-down single MEGA fuse holder and protective cover. MEGA fuses are engineered for safety, reliability, and compliance, using a Bakelite high-temperature body and tinned copper elements for low resistance and stable performance.

Rated for systems up to 72V DC with a 2500 A interrupt capacity (AIC), they’re ideal for lithium banks, inverters, chargers, and distribution circuits in vans, RVs, marine, and off-grid power.  They're also fully compatible with existing MEGA based systems.
