Product Description

The BUSSMANN Fuse Reducer (MPN NO.263-R) is a fuse reducer for cylindrical fuses, designed to fit fuse class RK1/RK5. It accommodates a fuse clip size of 60 A with a minimum fuse size of 0 A, enabling the use of smaller fuses in larger clip assemblies.

Frequently Asked Questions

What is a BUSSMANN fuse reducer used for?

A BUSSMANN fuse reducer adapts a larger fuse clip to accept a smaller fuse, enabling flexible circuit protection. It is commonly used in industrial panels and electrical distribution systems where fuse sizes must be matched to existing clip ratings without replacing the entire holder.

What are the specifications of the BUSSMANN NO.263-R fuse reducer?

The BUSSMANN NO.263-R fuse reducer fits fuse clip size 60 A and accepts a minimum fuse size of 0 A. It is designed for fuse classes RK1 and RK5. This reducer allows you to install a smaller fuse into a 60 A clip, providing versatility in overcurrent protection setups.
