Bussmann

<h3>Bussmann by Eaton: A Century of Circuit Protection Leadership</h3><p>Few names carry as much weight in electrical circuit protection as <strong>Bussmann</strong>. <a href="/1987-bussmann">Bussmann</a>, now operating as a division of Eaton, traces its roots to St. Louis, Missouri, where the Bussmann brothers began crafting fuses from the ground up — eventually supplying protection for horseless carriages and World War II aircraft alike. Today, that legacy spans more than 30,000 products and a global manufacturing footprint, making Bussmann one of the most trusted names in the industry.</p><p>Acquired by Eaton, a multinational power management company with nearly a century of innovation behind it, the Bussmann series has only grown in breadth and engineering depth. Eaton's mission to deliver intelligent power management solutions pairs naturally with Bussmann's long-standing focus on electrical safety and reliability. The result is a product portfolio that serves automotive, marine, RV, commercial, industrial, and alternative energy markets with equal confidence.</p><h3>Automotive &amp; Marine Electrical Protection You Can Rely On</h3><p>At the heart of the Bussmann lineup are its <a href="/1987-bussmann-fuse-2676">Fuses</a> — the first line of defense against damaging overcurrent conditions in any vehicle or vessel. From compact blade-style ATM and ATC fuses to high-amp cartridge and fusible link designs, Bussmann fuses are engineered to meet both OEM specifications and demanding aftermarket performance requirements.</p><p>Protecting those fuses and keeping them accessible is just as important as the fuses themselves. Bussmann's range of <a href="/1987-bussmann-fuse-holder-2688">Fuse Holders</a> — including inline blade holders, modular designs, and DIN rail-mount options — ensures secure, low-resistance connections in everything from daily drivers to off-highway equipment. For those who need to be prepared for unexpected blown fuses on the road or water, Bussmann also offers convenient <a href="/1987-bussmann-fuse-kit-10140">Fuse Kits</a> that bundle a practical assortment of amperage ratings into a single, organized package.</p><p>When a resettable solution is preferred over a one-time fuse, Bussmann's <a href="/1987-bussmann-circuit-breaker-2504">Circuit Breakers</a> deliver. Designed to match the footprint of standard ATM and ATC fuses, these ultra-compact breakers come in Type I (automatic reset), Type II, and Type III configurations, and are built to handle the voltage and current demands of trucks, RVs, ATVs, agricultural machinery, and more.</p><p>For multi-battery applications — common in RVs, marine vessels, and commercial vehicles — Bussmann's <a href="/23501-battery-isolator-bussmann-1987">Battery Isolators</a> provide a solid-state solution to a persistent problem: auxiliary battery drain. Acting as an electrical check valve, these isolators allow accessories to draw from a secondary battery without ever compromising the starting power of the main battery.</p><h3>Why Choose Bussmann?</h3><ul style="list-style:disc"><li>Nearly 100 years of circuit protection expertise and continuous innovation</li><li>Products engineered for automotive, marine, RV, commercial, and industrial environments</li><li>Backed by Eaton's global resources, engineering support, and power management technology</li><li>OEM-matched designs for straightforward replacement and compatibility</li><li>A broad catalog covering everything from miniature blade fuses to heavy-duty battery management</li></ul><p>Whether you're replacing a blown fuse on a weekend project vehicle or building out a complex multi-battery electrical system for a marine application, Bussmann has the circuit protection products — and the century of know-how — to get the job done right.</p>

Product Details

The Bussmann CBB30 is a 30-amp automatic reset thermal cycling circuit breaker designed for automotive, marine, and powersports electrical protection. This ATC blade-style breaker automatically resets after cooling when an overcurrent condition is cleared, eliminating the need for fuse replacement.

Key Features:

  • 30-amp current rating for medium to high-load circuit protection
  • Automatic thermal reset design cycles open and closed during overcurrent conditions
  • Standard ATC blade configuration fits most automotive fuse panels and holders
  • Includes mounting nuts and washers for secure installation
  • Engineered for long-lasting durability in harsh environments
  • Compact design allows installation in tight spaces

This circuit breaker provides reliable overcurrent protection for accessories, lighting circuits, winches, pumps, and other electrical loads. The thermal cycling action protects wiring and components while allowing temporary overloads to clear without requiring manual intervention.

Arrived promptly and in working order. Instructions were excellent.

Not only was it the lowest price on the net, the Amazon sign-in saved valuable time and ensured they were reliable. What impressed me even more was the delivery time, I've already gotten it! I did NOT expect to receive my air filter this quickly!

quick

quick and easy found exactly what i was looking for

Easy to use

I would not hesitate buy from Autoplicity again!!! A+++

Autoplicity won my loyalty as a customer on two separate counts. Firstly, I am always researching the web for the lowest possible price on an item even while I am in the process of actually ordering it. I had filled in all of my info on their order page and had competed almost everything required concerning making this order. All that was left to do was my clicking of the final 'link' actually confirming the order. At this point I totally stopped and looked elsewhere on the web. A couple of hours later I came back to my computer and was surprised to see an email from Autoplicity asking me why I hadn't fully completed my order and offering me 3% off the purchase price if I would complete it. I immediately finished and submitted the order without hesitation. Secondly, a day or so after I had made the order, I received another email from Autoplicity offering me an additional $5.00 rebate if I wrote a review of my experience with them. Do you think they really want me as a customer? YOU BET!! I like companies that do business like this. They know how to make and keep loyal customers.

Great

Great price and in stock, if shipping goes well, then stellar my review stays 5 stars.
