Bussmann NO.216-R Fuse Reducer, Fits Fuse Class RK1/RK5, For Fuse Clip Size 100 A, Min. Fuse Size 0 A

Fuse reducers for cylindrical fuses let smaller or lower-amperage fuses fit into larger fuse holders, blocks, or disconnect switches. They are used when a system needs a lower fuse rating, but the existing hardware is sized for a larger fuse. This allows for quick adjustments without replacing the entire fuse holder. These adapters are easy to install and help maintain a secure electrical connection. They support safe operation by keeping the fuse properly aligned and enclosed. Fuse reducers are available for many fuse types and sizes, making them a flexible and cost-effective solution for updating or modifying electrical systems.
