## Overview

The Cooper Bussmann NO 263 Non Rejection Pair Cartridge Fuse Reducer enables the installation of a 30A fuse into a 60A fuse block, simplifying equipment conversions and maintaining proper circuit protection without the need to replace fuse blocks. Rated for 600 volts and packaged securely, it offers a compact, cost-effective solution for professional electrical applications.

## Description

Pair Cartridge Fuse Reducer, Non Rejection, 60A To 30A, Boxed. Fuse reducers allow a smaller size fuse to be installed in a fuse block intended for a larger fuse. For example: a 30 amp fuse is two inches long and will not fit into a 60 amp fuse block (which is three inches betweenclips). A NO.263 reducer installed on the fuse permits it to be installed in a 60 amp fuse block. Reducers are particularly useful when equipment is being converted. Proper protection can be maintained without the expense of replacing the fuse block. Catalog numbers with the "-R" suffix (NO.263-R fit rejection (Class R) fuse blocks. Consult factory for 600 volt and Class J reducers.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great parts! Work great. Solid.
*by M***E on October 22, 2021*

I bought these to put some 20 amp fuses in a disconnect box and they fit very tight and very secure and I’m quite happy they are a little pricey but they are extremely specialized. You get what you pay for.

### ⭐⭐⭐⭐⭐ Solves the issue of smaller fuses in a 60 amp slot
*by E***Y on February 12, 2024*

I upgraded my HVAC condenser, and the new one only needs 40 amps max. Changed out the breaker, but the disconnect still had 60 amp fuses. I bought 40 amp fuses, but they were too small. These reducers solved that problem. You will need 2 of these (one for each phase).They are a bit tight, so you have to put some force. I suggest putting in the harder side first, so you can use a mallet to get it in.

### ⭐⭐⭐⭐⭐ Convert Fuse Box from Older 3" Cartridge Ffuse to Newer 2" Fuse
*by T***E on January 27, 2014*

These push on to each end of a 2" cartridge fuse to allow it to fit in the space reserved for a larger diameter 3" cartridge fuse. The fit is tight so some effort is required to push it fully on. There is a tab inside to stop it from over sliding.I installed a higher efficiency AC unit and could not get fuses small enough to meet the recommended fuse size in the old 3" length. These solved the problem without an expensive and unnecessary fuse box replacement.Shipping was expensive, but the overall price was right.
