SKU: 540-0072


Magnum, 300A Fuse Block Assembly, 48VDC, Class T, ME-300F

Over-current protection is provided by Magnum Energy Fuse Block assemblies, which are code-compliant. Short circuits and overloads can harm the battery bank, inverter, and cables, so they're used to secure them. Each Fuse Block Assembly contains a fast-acting, current-limiting fuse cartridge that provides immediate safety in the event of a short circuit while also allowing for momentary current surges that are typical in inverter applications. Durability, ease of installation, and good looks are all supported in a lightweight, cost-effective package by a durable injection-molded polycarbonate base and thermoformed ABS cover.

The ANL type fuse is used in the 125 and 200 amp models, while the Class-T fuses are used in the 300 and 400 amp models. Magnum fuse blocks are suitable for applications where high-current components, such as inverters and chargers, need over-current safety.
