White ceramic Renogy MRBF terminal fuse marked 75A 58V beside its silver M8 bolt

The Renogy MRBF Terminal Fuse Adds Compact High-Amp Circuit Protection Right at Your Battery Terminal

The Renogy MRBF Terminal Fuse is a compact fuse that protects DC circuits at the positive battery terminal. It comes in 11 current ratings from 30A to 400A and is rated for 58V.

It is for solar, RV, marine and off-grid builders who want circuit protection without a separate inline fuse holder. Renogy says it attaches directly to the positive terminal's copper plate.

Renogy MRBF Terminal Fuse Features

Fits Directly on the Terminal

Renogy says the fuse attaches directly to the positive terminal's copper plate for circuit protection, with no external connections needed. It has a 5/16 in (M8) mounting hole, and an M8 terminal bolt is included.

11 Current Ratings

Choose 30A, 40A, 60A, 75A, 100A, 150A, 200A, 250A, 300A, 350A or 400A to match your circuit. The rating is printed on the fuse body along with the 58V rating.

High Interrupt Ratings

Renogy lists interrupt ratings of 10,000A at 14VDC, 5,000A at 32VDC and 2,000A at 58VDC.

Ceramic Body and PES Cover

The insulating body is ceramic and the cover is PES. Renogy lists RoHS, UL and CE certifications.

Real-World Applications

Battery terminals. Fuse the positive terminal of a battery in a DC system.

Renogy 500A Combiner Box. Renogy says the fuse simplifies wiring with its 500A Combiner Box, and the included M8 bolt helps you install it there.

Practical Comparison

Terminal Fuse Versus Inline Fuse

An inline fuse needs its own holder and cable connections. Renogy says this terminal fuse attaches directly to the terminal's copper plate, so no external connection is needed.

Buyer Guidance

Choose the Right Rating

Pick the current rating that fits your circuit and cable, and make sure the system voltage is within 58V. If you are not sure which rating to use, ask the Outbound Power team.

Holder or Combiner Box Required

Renogy says that if the fuse is not used with a combiner box, a terminal fuse holder is required.

This May Be A Good Fit If

You want a fuse mounted at the battery terminal
Your system runs at or below 58V DC
You plan to use a Renogy Combiner Box or a terminal fuse holder

Exactly what I ordered

Exactly what I ordered. Great quality and the updates that are given as to when it was shipped and when it should arrive is amazing.

Generator works

Generator works. Have yet to try solar panels. Will have to wait for a sunny day! Just wish I was more tech-savvy. Feel a little overwhelmed… but I am satisfied w purchase

It charges the battery on a cloudy day

This battery charges lightning fast has a light and multiple charging ports and two sockets. It has 2 way power, from the solar panel and the wall outlet. Definitely purchasing from this seller again

Trusted Since 2025 – Highly Recommended!

The generator cord looks longer in the pictures than in real life. It is 18” long from tip to tip. I received the cord on time and in excellent condition. I have not used the cable at this time as it is for power outages only. I’ve recommended Outboundpower.com to everyone for a vender of solar and power station equipment. They have been a favorite of mine since 2025.

Hi Homer, thanks so much for the kind recommendation and for trusting us for so long! We’re glad your adapter arrived on time and in excellent condition. Thank you for your note about the length and hope it’s ready when you need it. We appreciate you!

Was wrong about last review

Email discomunication and other led to my last review,when spending a lot on solar equipment I was lead to believe what my sales person had told me,,they said they would send a email where I could get a discount for my purchase,I waited patiently and it never came,so I thought I could trust them and made the purchase anyway hoping for the adjustment,I finally got it,but they have reach out to me,and because they do so much business they get tided up with other things,I believe that are the best people to buy solar from,things just got of hand,please know that they have done an excellent job for me and others

Hi Todd, thank you for updating your review and for your kind words. We’re sorry for the email miscommunication, but glad we were able to follow up and get it sorted out. We truly appreciate your patience and trust, and we’re grateful you chose us for your equipment!

First class treatment by Outbound Power

I give this a five star rating because of the service that jam help me with,, generators, batteries, solar panels, wires, breakers, shut off everything, and I am not an expert at putting this all together, but she straightened me right out. Oh, I had to do is get my electrician to hook up to my breaker box which wasn’t a big deal rest was very easy,, and jam also helped me with the pricing and it was just the first class Five Star Job by Outbound Power I love him and if I get anything else, it will definitely be from jam and Outbound power company.
