Victron Energy CIP137300010

The Victron Energy MEGA-fuse 300A/58V is an essential component for high-performance electrical systems, specifically designed for 48V applications. With its robust construction and high capacity, it plays a crucial role in safeguarding your electrical setup against overloads, ensuring reliability and safety. This fuse provides peace of mind and enhances the overall efficiency of your power distribution system.

Product Features

Dovetail Feature

The dovetail feature integrated into the Victron MEGA-fuse holder allows for seamless interlocking of multiple fuse holders. This innovative design simplifies installation and enhances organization within your electrical system, making it an ideal solution for both commercial and residential applications.

High Current Bus Bar Options

With options like a five-position high current bus bar capable of handling up to 500 A and a six-position version for 1500 A, the Victron MEGA-fuse holder supports substantial current flows. This flexibility makes it suitable for applications that require high power, such as Multi or Quattro inverter/chargers.

Versatile Fuse Holder Design

The Victron MEGA-fuse holder is available in configurations both with and without a cap, providing versatility based on your installation needs. This adaptability allows for optimal wiring setups while maintaining safety standards.

Stacked Fuse Holder Configuration

Designed for efficiency, the stacked fuse holders come with copper bus bars in both five and six-position options. This significant feature aids in consolidating your power distribution and reduces the footprint of your electrical installation while ensuring maximum performance.

High Voltage and Low Resistance Performance

This MEGA-fuse delivers exceptional performance at 32V and 58V systems with low voltage drop and cold resistance, making it a reliable choice for powering various devices. Users can trust in its quality to maintain operational integrity across their electric systems.

How It Works

The Victron MEGA-fuse operates by interrupting current flow in the event of an overload, protecting sensitive components of your electrical system. Ideal for both new installations and upgrades, this product enhances the safety and reliability of your energy solutions.

Fuse Operation Mechanism

When the current exceeds the designated threshold, the fuse element melts, breaking the circuit. This process immediately stops power flow, safeguarding your electrical equipment from damage caused by excessive current.

Connection Stability

The robust M10 input connections ensure solid and stable integration with your electrical system, reducing the risk of connection-related failures. This stability is crucial for maintaining the integrity of high-current applications.

Enhanced Safety Features

The design of the Victron MEGA-fuse includes features that promote excellent thermal management, minimizing the risk of overheating. This focus on user safety is paramount, especially in high-demand scenarios.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
