Space-Saving High-Amperage Circuit Protection

*Please note Blue Sea fuses are manufactured by Eaton, Bussman or Ionnic and may have labelling of one of these manufacturers on the product and/or packaging.

The Blue Sea Marine Rated Battery (MRBF) Dual Terminal Fuse Block solves one of the most common challenges in marine and automotive electrical installations: limited space. By mounting directly onto the battery terminal, this fuse block eliminates the need for short, difficult-to-install cable runs between the battery and a traditional firewall-mounted fuse holder. This design not only saves valuable room in crowded battery compartments but also reduces resistance and potential failure points in your high-current cabling.

Engineered for demanding environments, this unit is ideal for protecting high-load circuits such as inverters, windlasses, and bow thrusters. With a maximum voltage rating of 58V DC, it is perfectly suited for modern 12V, 24V, and 48V electrical systems found in boats, caravans, and off-grid 4WD setups.

Direct Battery Terminal Mounting

The primary advantage of the Blue Sea Marine Rated Battery (MRBF) Dual Terminal Fuse Block is its ability to interface directly with the power source. It is designed to mount securely onto a standard 3/8" (Approx. M10) battery terminal stud. By fusing the circuit right at the battery post, you ensure maximum safety; if a fault occurs in the main cable running to your equipment, the fuse will blow immediately at the source, preventing potential fire hazards associated with unprotected live cables.

Versatile and Robust Design

Constructed with marine-grade materials, this fuse block is built to withstand the harsh conditions of the Australian outdoors. The hardware includes stainless steel studs and tin-plated copper bus bars for maximum conductivity and corrosion resistance. The unit features M8 (Approx. 8mm) studs for connecting your load cables, accommodating heavy-duty lugs and cabling required for loads up to 300A.

Safety is paramount in high-current applications. The included insulating cap prevents accidental shorts across the conductive terminals, satisfying ABYC/USCG requirements for insulation when installed correctly. The versatile design allows for flexible cable orientation, making it easier to route heavy gauge wire in tight lockers.

Dual Circuit Capability

This model features a dual-terminal design, allowing you to fuse two independent circuits from a single battery post. This is exceptionally useful for running a main DC switchboard feed and a separate inverter charger feed from the same battery bank without stacking multiple ring terminals on the battery stud.

Key Features

  • High Interrupt Rating: Safely handles high amperage loads up to 300A.
  • Compact Footprint: Mounts directly to 3/8" (Approx. M10) battery studs, saving panel space.
  • Voltage Versatility: Rated for 58V DC, suitable for 12V, 24V, and 48V systems.
  • Secure Connections: Uses M8 (Approx. 8mm) output studs for secure cable termination.
  • Safety Cap: Insulating cap protects against accidental short circuits.
  • Corrosion Resistant: Tinned copper and marine-grade stainless steel hardware.

Whether you are refitting a yacht or building a custom tourer, the Blue Sea Marine Rated Battery (MRBF) Dual Terminal Fuse Block provides professional, reliable, and neat circuit protection exactly where you need it.

Secure your high-current electrical system today with this compact terminal fuse solution.

A book with so much heart
Format: Kindle
An absolutely delightful story with the perfect amount of spookiness. Light-hearted but also deep in its exploration of the ways we push down our own souls because of what we think others need.

Spooky Middle Grade Book
Format: Hardcover
I cannot explain how excited I was to hear that Ash Van Otterloo was putting out another book. I was a big fan of Cattywampus and was very excited once I read the summary of this book. I requested and was granted an ARC copy of this book by Scholastic in exchange for a fair and honest review. I don’t think I have the exact words to express how much I adore this book. I’ve only recently discovered that as an adult I can actually enjoy middle grade books and this book has probably become one of my new all-time favorite books ever. One of the biggest things that I adored about this book is the characters. Tennie is an absolute sweetheart who is way to willing to give up and hide pieces of herself for the sake of keeping the peace. It’s sweet and heartbreaking at the same time. I also love towards the end when she gets some fire in her. Fox was also quite a character. They’re kind of a bit much at times, but they’re also aware of their faults. They know that they can forget things and that they might annoy their friends, but they also try to soothe things over. I honestly really liked them, and it was really nice to see a character using they/them pronouns so casually. The two characters had a really nice dynamic with each other. They grew close quickly, the way kids do, and delved into a ghost hunting adventure. It was honestly really cute and heartwarming to watch them grow closer. This also felt really good because of Tennie and her desire to always be the peacekeeper. She even considered being friends with Fox and exploring the forest together as her being “selfish”. I just really loved it and their interactions made me so happy. It wasn’t always great, but it just gave me so much joy and I was constantly smiling. I did not expect to love the atmosphere that was created in this book. It was sufficiently spooky without being necessarily scary. It worked really well in the town of Howler’s Hollow. Howler’s Hollow is a town in the rural south, somewhere that’s not always popular with the LGBTQ+ community. The thing is, I don’t know if this book would have worked as well in other locations. It’s one of those towns where everyone seems to know everyone. It appears to be relatively close-knit, even if the people don’t always get on, and it has a great forest. The forest allows the atmosphere to be appropriately creepy while the people in the town add a source of information for Tennie and Fox. It was also built up very well and created an atmosphere that led to a great payoff at the end. I cannot fully encapsulate everything that I love about this book, but I will recommend it to everyone who asks. This book is fun and whimsical with a dark edge and serious topics that need to be explored. It might hurt at times when things are discussed, but it has a happy ending.

Magic, Mayhem, Ghosts and First Love!
Format: Hardcover
This book has it all: amazing Halloween feels, magic gone awry, ghosts wreaking havoc, family secrets, and even a delightful first crush! As a middle child, Tennie thinks it's her job to keep her big, rambunctious family in order, but she could really use a break. So she's thrilled when she gets the chance to stay with her grandma, away from all the family chaos, but that changes when she accidentally unleashes a whole host of restless spirits. And what's more, those spirits have something to tell her about grandma's mysterious new boyfriend, a secret that might upend everything she knows about her family and their beloved mountain home. This book is teeming with beautiful odes to nature and delightfully folksy language that draws readers into the cozy, bucolic Appalachian setting. The friendship and budding romance between Tennie and Fox shines off the page, and readers will experience all of the tingles, speed bumps and awkwardness of a first crush. Van Otterloo weaves a poignant tale about families going through tough times but ultimately finding hope and strength in each other, and, of course, it's all suffused with a delightful dose of oh-so-cozy magic. Layered alongside the family tale is an important storyline about protecting nature and valuing the "small" lives of country folk, which we can see by the end of the story are anything but small.

Folksy, spooky, downright darling
Format: Hardcover, Format: Hardcover
Oh my goodness, this book. Ash Van Otterloo is quickly becoming one of my insta-read authors. Their folksy, spooky, downright darling stories are such a joy to read! A TOUCH OF RUCKUS was magnificent. I adored Tennie and Fox's relationship, the ghosts were creepy as heck, and the setting of a small, mountain-side town was as charming as ever. If I could eat pizza, I would have taken a bookstagram pic with it and this book! Boy, did it make me hungry!! 🍕
