What Are Internal SuperFuses?

Russ Andrews Internal SuperFuses are a development from our UK mains plug SuperFuses we offer as a replacement for the standard fuses found in the plugs of UK power cables. They were so successful that we decided to apply the same process, which gives the Superfuse it's unique performance, to develop a replacment for the internal fuses commonly found in components such as CD players or amplifiers. 

Superfuses undergo the unique Process-Q™ and are then hand-treated with DeoxIT
® contact enhancer. They are suitable for fitting to any piece of Hi-Fi equipment which carries the same value internal fuse.

What's Included?

When you buy our Internal SuperFuses, we include a DeoxIT Gold wipe in addition to the fuse itself. This allows you to treat the fuse and the fuse holder with the contact enhancer just before you fit it. 

SuperFuse contents

We also include a 'Fitted with Russ Andrews SuperFuse‘ label to attach to your equipment casework so you can keep track of where you have fitted your upgraded fuses. 

Full fitting instructions are included and the fuse is supplied in a protective pouch 

Internal SuperFuse Values

Internal SuperFuses are available in slow blow (timed) or fast blow versions. We have a range of values available in both types from 100mA to 6.3A and internal fuses must be replaced with a SuperFuse of the same value and type. The value of the fuse should be stamped on the end cap of the fuse, though you may need a magnifier to see it: Slow blow fuses will be prefixed with a 'T' before the value - e.g. T 3.15A.

Fitting Internal SuperFuses 

SuperFuses are a straight swap for existing fuses. To replace internal fuses with our SuperFuses, you may need to consult your equipment manual to find out how to replace them. If you are lucky, you will find the internal fuse is built into the IEC socket on the back of your component, or on the back panel, and it's easy to swap it without opening your equipment's casework - see below.

Fitting an Internal SuperFuse

In other cases, it may be that the fuse is fitted internally and you need to remove the casework lid to get access to it. Remember, it's important to replace your fuses with a SuperFuse of the same value and type.

100% Satisfaction Or Your Money Back

 

 
Remember that internal fuses are designed to fail in the event of a fault occuring in the equipment they are fitted in. This is for safety and may indicate a fault with the component. SuperFuses are, therefore, excluded from our Lifetime Warranty. 

However, we're so confident that you'll be happy with the performance of your new SuperFuse that they are covered by our 60 Day Money Back Guarantee, which means you can audition them in your own system for up to two months - and if you’re not 100% satisfied with the improvements, you can send them back for a full refund. You can’t say fairer than that, can you?
