Bussmann UCB-6 Automotive Circuit Breaker, Type I, 6A, 12 Vdc

The Bussmann UCB-6 is an automotive circuit breaker built to the Type I series footprint, giving it a standardized mounting profile that matches common automotive circuit protection layouts. Rated 6A at 12 Vdc, this breaker features a snap-off universal blade terminal and a plain (non-color-coded) housing, making it a straightforward drop-in replacement for automotive, marine, and low-voltage DC circuits that call for a Type I footprint breaker at this amperage.

Key Features

  • Type I Series Footprint: Matches the widely used automotive Type I circuit breaker footprint for straightforward fit and replacement in existing mounting locations.
  • Snap-Off Universal Blade: The universal blade terminal is designed to snap off, allowing the breaker to be adapted to different terminal or mounting configurations as needed.
  • Color Code Plain: Housed in a plain, non-color-coded body rather than an amperage-specific color scheme, simplifying stocking where visual color coding is not required.
  • Amperage Rating: Rated 6A for circuit protection sized to lower-current automotive and DC accessory circuits.
  • Voltage Rating: Rated for 12 Vdc systems, matching standard automotive and marine 12-volt electrical architecture.
  • Automotive-Grade Circuit Breaker: Provides overcurrent protection for 12 Vdc wiring circuits, helping guard connected components and wiring from damage due to sustained overcurrent conditions.
  • Direct-Fit Replacement: The Type I footprint and universal blade terminal are designed to simplify swapping out a failed or mismatched breaker without reworking the existing wiring harness, saving diagnostic and repair time.
  • Compact Automotive Form Factor: Sized to fit standard automotive Type I mounting locations, including fuse and relay panels, junction boxes, and dedicated accessory circuit housings.

Typical Applications

  • Automotive 12 Vdc Circuit Protection
  • Marine and RV Low-Voltage Wiring
  • OEM and Aftermarket Circuit Breaker Replacement
  • Accessory Circuit Protection in Type I Footprint Locations
  • Low-Amperage DC Branch Circuits
  • Fuse and Relay Panel Circuit Protection

Why Bussmann?

Bussmann circuit breakers are built to standardized footprints like the Type I series, so professionals and DIY installers can source a direct-fit replacement with confidence rather than reworking an entire wiring harness. The UCB-6's snap-off universal blade design adds mounting flexibility, while its 6A, 12 Vdc rating keeps it matched to the automotive and marine DC circuits it's intended to protect. Choosing a Bussmann breaker means relying on a recognized name in circuit protection for dependable, code-appropriate performance in demanding automotive electrical systems where consistent, repeatable overcurrent protection matters.

Bussmann UCB-6 – Frequently Asked Questions

1) Will a Bussmann UCB-6 breaker drop into an existing Type I circuit breaker location?
Yes. The UCB-6 is built to the automotive Type I series footprint, so it mounts in the same locations a Type I breaker already occupies, including fuse and relay panels, junction boxes, and dedicated accessory housings. Combined with the universal blade terminal, that means you swap the breaker without reworking the harness.
2) What amperage and voltage is the Bussmann UCB-6 rated for?
6 amps at 12 Vdc. That sizes it to lower-current accessory and branch circuits on standard 12-volt automotive and marine electrical systems, not to high-draw loads like winches or inverters. If the circuit you are protecting draws more than 6A continuous, you need a higher-amperage breaker in the same Type I family.
3) What does the snap-off universal blade on the Bussmann UCB-6 mean for installation?
The blade terminal is a universal style that snaps off, so the breaker can be adapted to different terminal or mounting configurations instead of being locked to one connection style. Practically, you fit it to what the vehicle already has rather than modifying wiring.
4) Should I use a Type I automotive circuit breaker or just a blade fuse?
A fuse is one-time: it opens and you replace it. A Type I breaker like the UCB-6 is the resettable route for circuits that nuisance-trip or sit where a blown fuse is awkward to reach, and it mounts into the standard Type I footprint used across automotive circuit protection layouts. For a circuit that should stay dead once it faults, a fuse is the simpler part.
5) Why is the Bussmann UCB-6 housing plain instead of color coded by amperage?
The UCB-6 uses a plain, non-color-coded body rather than an amperage-specific color. Nothing about protection changes, but you cannot identify the rating at a glance, so mark the circuit or check the stamped rating when you stock several amperages together. Some fleet shops prefer plain housings precisely because it simplifies stocking.
6) What is the exact part number to order for the Bussmann 6A Type I automotive breaker?
Order Bussmann UCB-6. That is the manufacturer part number, and the model covers the 6A, 12 Vdc Type I breaker with the plain housing and snap-off universal blade.
