To fully understand the potential benefits of Swiss Digital Fuse Box, we must first examine the pitfalls of the fuse.
A fuse is a simple, sacrificial device used to protect your component in case of electrical failure. When current is being drawn through the fuse, it begins to heat up, and in cases of excess current or short, it will melt and sever the connection to power. While this works to protect your devices, a common fuse leaves much to be desired in means of performance when it comes to our audio components.
Regardless of the size of the power cable feeding even your largest amplifiers, the live line feeding the power supply eventually becomes constricted to the single small filament housed in the fuse. Current draw through the filament causes heat, which in turn raises the resistance and limits the capability of the power supply as it digs deep to replenish its reserves in times of high demand and musical transients.
Our elegant solution is the Swiss Digital Fuse Box. After carefully reading the instructions, the restrictive fuse is replaced with a Sluggo, a very low resistance and high current capable metal rod made from high purity materials. Run a power cable from the wall to the Swiss Digital Fuse Box IEC C13 inlet, and then plug your component into the Fuse Box’s NEMA 15 receptacle and you are ready to experience what the Fuse Box has to offer.
Each Fuse Box is programmed at the time of ordering to match the manufacturer’s fuse specification for your device. An internal microcontroller magnetically monitors the current draw and opens the circuit via a low resistance relay if it exceeds the pre-programmed setting. Resetting the Swiss Digital Fuse Box if tripped is done simply by disconnecting it from the wall for a minimum of 15 seconds. Fuse Box will not lose its programming ever, and will continue to protect your device faithfully and without fault.
Please Note: We can program Swiss Digital Fuse Box for the voltage and frequency of your country, but all Fuse Boxes have a US style plug output and will require the appropriate power cable. Please see our Piggy Tail power cables if you need a short length cable for this purpose.
Sluggo
Sluggo is precision manufactured in the size of your typical 5x20mm or 6x32mm fuse, made out of your choice of high purity materials. All the sonic benefits of an audiophile fuse without the worry of an expensive failure. One Sluggo in either high purity brass, copper, or gold immersion (Super Sluggo) included with the purchase of the Swiss Digital Fuse Box. Additional Sluggo are available here.
High Purity Brass - Some power cable manufacturers utilize high purity brass terminations or gold immersed brass, and matching like metals can create an incredible pairing. This is our base model Sluggo.
High Purity Copper - Nothing but pure high purity copper in the conductor path providing all the benefits of Sluggo without imparting anything to the sound.
Super Sluggo - All of the benefits of high purity copper immersed in gold for greater warmth and immediacy. This is our standard and recommended Sluggo for starting out with Swiss Digital Fuse Box.
Super-Duper Sluggo - A tellurium copper Sluggo has been plated with Rhodium, our hardest plating that adds more of a sonically neutral aspect, leaning towards colder tonality to help fine tune your system
Graphene Sluggo - Graphene is a super conductor with up to 70% greater conductivity than copper, offering the closest thing to no fuse at all! Our TOL and highest recommended Sluggo. Ask us about a 20% discount to upgrade to Graphene for current Swiss Digital Fuse Box owners!
Piggy Tails
Swiss Digital Fuse Box has an IEC C13 inlet, and a NEMA 15 outlet on the other side. This allows you to use your performance power cable of choice to feed the Fuse Box, and still allows you to enjoy the benefits if you have an integral power cable on your audio component.
We offer quality and affordable Piggy Tail power cables in various geometries and materials that have proven to provide great performance and sound quality.
Piggy Tail - 1ft length of the Core Power Diamond power cable with 9 separate cores of 16 gauge 8N OFC copper plated with 70 microns of extruded pure silver. Available in Schuko or US termination.
Extreme Piggy Tail - Building off of the performance of our base model Piggy Tail, the Core Power Diamond Extreme is a 1ft power cable featuring double the cores of silver plated oxygen-free copper for even lower resistance and higher current capability.
Try the Swiss Digital Fuse Box for yourself in your own home. All products sold by Vera-Fi Audio are covered by a 30 day money back guarantee should you be dissatisfied in any way.

Swiss Digital Fuse Box - "What headroom sounds like"
Frequently Asked Questions (FAQs)
What is the Swiss Digital Fuse Box (SDFB)?
The SDFB is a device designed to improve the performance of your audio equipment by eliminating the weakest link in every system, which is the Fuse. The Fuse degrades with time and actually imparts an Impedance in and of itself. The SDFB is MicroProcessor Controlled and uses a State-of-the-Art Hall Effect Sensor to PROTECT your equipment.
How does the SDFB enhance audio performance?
By replacing conventional fuses with a metal rod called Sluggo, the SDFB reduces resistance and allows for better current flow, leading to improved midrange and treble clarity, increased power handling, and a more defined soundstage. We can promise a more refined bottom end as well.
Is the SDFB compatible with all audio equipment?
The SDFB is designed to be compatible with a wide range of audio equipment. However, it's essential to verify compatibility with your specific devices before installation. Please contact us here. Fuse Box works with gear rated at 500mA to 12 amps, with either Fast or Slow Blow varieties.
How does the SDFB provide protection without a traditional fuse?
The SDFB utilizes a microprocessor coupled to our precision Hall Effect Sensor / and Relay to monitor power flow, automatically opening the circuit in case of anomalies, thus providing protection without the need for a traditional fuse.
Can the SDFB be used in European audio systems?
Yes, SDFB is available in three voltage configurations:
- 110v, 60Hz
- 220/240v, 50Hz
- 220/240v, 60Hz (rare but used in a few parts of the world)
For users in the EU or parts of Asia, we recommend the following setup to ensure optimal performance without the need for adapters:
- Input Connection: Use your existing power cord to connect the wall outlet (whether Schuko or 3-blade US plug, as used in some regions) to the input side of the SDFB.
- Output Connection: Consider using one of our NEMA 15-type Piggy Tail power cables to connect the output of the SDFB to the IEC input of your audio equipment.
This configuration has been successfully implemented by over 200 SDFB users in the EU, delivering safe and exceptional results.
By following this setup, you can seamlessly integrate the SDFB into your system, enhancing performance while maintaining safety and compatibility.
What is the role of the Piggy Tail power cable in the SDFB setup?
The Piggy Tail is a short power cable designed to connect the SDFB's output to your audio equipment's power input, ensuring a secure and efficient connection.
Does the SDFB require any special installation procedures?
Installation of the SDFB involves replacing the existing fuse with the provided solid copper rod and connecting the device using the appropriate power cables. It's recommended to follow the manufacturer's installation guidelines or consult a professional.

Great communication. Excellent product! Would not hesitate to purchase again. A+++
The Graphene is a worthwhile upgrade from the copper or brass SLUGGOs. I've got 3 and will order 2 more. Highly recommended!
These Piggy Tails are Excellent. You might think adding them to your favorite Power Cords (I use Rick Schultz Emersion), will be a little of a downgrade but, you will be gaining a HUGE BOOST in performance because of the Sluggos passing on that Sweet Power to your Electronics.
A Win Win all the way.
I had ordered 2 SDFB for my Amps. Due to some confusion, I received the wrong ones. I checked back with Mark and, I was instructed not to use them and to send them back. Vera-Fi will ALWAYS make sure that, you are using the correct Spec items. They took care of me all the way.
The SDFB Really adds that extra layer of Life to my System. There is Excitement when every I listen.
Good Company… they deliver
Let me start out by saying I'm not an audiophile, just an old guy who had the chance to buy some decent speakers. I shopped around watched hours of YouTube evaluations and made my choice. These are very solid speakers that look good anywhere.
As I said, I'm not audiophile but these things blew me away with the room filling sound from a compact size. I also added the Bluetooth amps so I can put them in any room by just plugging them in.
I would recommend these to anyone looking for great sound at a great price.
Fantastic: Mark is the Boss
It took a while to get them, but it was definitely worth the wait. For the price, these were way better sounding than I was expecting. Beautiful heavy wood cabinets, excellent range, tone and quality construction. I don’t think you’d need to, but a nice addition that I purchased was the Vanguard Caldera 12 inch subwoofer. It certainly complimented the system well. I didn’t want to spend a fortune and these fit the bill perfectly.
The customer service response was outstanding and prompt. I haven’t seen this level of personal customer attention in a long time. Highly recommend.
I have mine for a week or so; I have more on order, including the Snubway. But just this one unit has made an impact for the positive, so I am hoping to build on this. It is outlet d, and depending on which outlet it is plugged into, the results can vary, depending on the outlet position in the room. I put my in the Garage by the 1st AC outlet n to the fuse box after reading on that would be a good place for one unit, and they were right, right away the TV Sound bar and the 3 subwoofers connect sounded more dynamic, and the sound was more natural and with more body, what surprised me was on the 2nd level where my Stereo is it made a positive impact there also, I went down and unplugged it and went up and listened again and there was a drop off in presence, body and weight to the music as well as lacking the detail, piano is what I used with a stand up bass, to keep it simple, all sound more real with the one unit plugged into the outlet by the fuse box, so one is staying when I get the others I will built from there and see the extra ones impact, Mark is going to send me a package that he feels will work best for my system, Mark been great even took the time to call me to answer some questions on his products and which would be best for my needs. So try different outlets, let the unit burn-in for a week or so, the only time it hurt the sound was when I put it in the outlet before the Core balanced line conditioner; those two did not play nice together at all, lost mid-bass and bass, sound was thin, but that was the only time, I will try a Snubway there when I receive it. A good product, give it a try.
