Materials and build readiness

The unit combines a robust PA66-RG301 thermoplastic body with corrosion-resistant stainless steel hardware. The fuse uses a copper alloy element with nickel plating for durability, while the fuse housing is a clear PES plastic. This blend supports long-term use in demanding environments, including exposure to heat and moisture variations.

Protection, safety, and environment

Designed for ignition protection in constrained spaces, the MRBF fuse holder helps manage current safely in DC systems. The IP66 rating guards against dust and water intrusion, making it suitable for vehicles, boats, and rugged machinery where exposure is possible.

Typical applications

Ideal for DC power distribution in modern vehicles and equipment. Use cases include EVs, RVs, marine applications, windlasses, cranes, batteries, and charging stations where a compact, reliable fuse holder supports critical power circuits.
