Magnum Energy Fuse Block assemblies are designed to provide code compliant over-current protection. They are used to protect the battery bank, inverter and cables from damage caused by short circuits and overloads. Each Fuse Block Assembly uses a fast acting, current limiting fuse cartridge which provides instantaneous protection in the event of a short circuit, but also employs a time delay to allow momentary current surges common in inverter applications. A rugged injection molded poly carbonate base and thermoformed ABS cover provides durability, easy installation, and good looks all in a compact, cost effective package.

The 125 and 200 amp models use an ANL type fuse and the 300 and 400 amp models use the Class-T fuses. Magnum fuse blocks are ideal in applications where over-current protection is required for high current components such as inverters and chargers.
