Complete guide to the Eaton BR130 30-Amp Single-Pole Circuit Breaker
The Eaton BR130 is a Type BR single-pole circuit breaker rated for 30 amps at 120/240V AC. It's a workhorse component used in residential load centers to protect branch circuits from overloads and short circuits. Designed to snap directly into Eaton BR and CH series panels, it's one of the most widely stocked breakers in North America and a frequent choice for both DIY electrical work and professional installations.
TL;DR: The Eaton BR130 is a reliable, single-pole 30A breaker built for Eaton BR/CH load centers. It's commonly used for dedicated high-draw 120V circuits or paired with another single-pole or used as a two-pole when 240V protection is needed. Confirm panel compatibility before purchase.

Who this breaker is for
The BR130 is intended for homeowners, electricians, and facility maintenance staff who need a dependable 30A single-pole breaker for use in an Eaton BR or CH panel. Common scenarios include replacing a tripped or aged breaker on an existing 30A circuit, adding a dedicated circuit for a specific appliance, or building out a new load center.
Typical applications
- Dedicated 120V/30A circuits (rare, but used in some workshop or RV-related subpanels)
- Paired as part of a two-pole 240V configuration for water heaters, baseboard heaters, or dryers (when the panel supports tying two single-poles, though a true two-pole BR230 is generally preferred)
- Subpanel feeder protection where 30A is appropriate
- Direct replacement of an existing failed Type BR 30A breaker
Important: For most 240V appliances (electric dryers, water heaters, ranges), code generally requires a true two-pole breaker such as the Eaton BR230. Do not substitute two BR130 breakers with a handle tie unless your installation specifically permits it and complies with local electrical code.
What to check before you buy
1. Panel compatibility
The BR130 fits Eaton BR series load centers and is also compatible with Eaton CH series panels in some applications, but it is not interchangeable with Square D QO/Homeline, Siemens, GE, or other manufacturer panels. Check the label inside your panel door for the list of approved breakers.
2. Amperage and wire sizing
A 30A breaker requires a minimum of #10 AWG copper conductor for the branch circuit. Using undersized wire is a serious fire hazard. If you're upsizing from a 20A circuit, you'll likely need to rewire the run.
3. Single-pole vs. two-pole
If your appliance needs 240V, you want a two-pole breaker (BR230), not a single-pole BR130. A single-pole breaker only occupies one slot and connects to one bus bar phase.
4. AFCI / GFCI requirements
The standard BR130 is a thermal-magnetic breaker without AFCI or GFCI protection. Modern code (NEC) requires AFCI or combination AFCI/GFCI protection on many residential circuits. Verify whether your application requires an AFCI/GFCI variant instead.
Pros and cons
Strengths
- Widely available at major home improvement retailers
- Simple plug-on installation in compatible panels
- Trusted, established Eaton Type BR product line
- Competitively priced versus other major brands
- 10,000 AIC interrupting capacity suits most residential service
Limitations
- Only compatible with Eaton BR (and certain CH) panels
- No built-in AFCI or GFCI protection
- Single-pole only — not suitable alone for 240V loads
- Counterfeit units occasionally appear; buy from reputable sellers
Installation overview
Installing a breaker is straightforward mechanically but involves working in a live electrical panel. If you are not trained and confident, hire a licensed electrician.
- Shut off the main breaker to de-energize the bus bars. Branch wiring upstream of the main may still be live.
- Verify power is off with a non-contact voltage tester at the bus.
- Remove the panel deadfront cover carefully.
- Align the BR130 with an empty slot, hook the back tab onto the panel rail, and firmly press until it snaps onto the bus.
- Strip the branch conductor (typically #10 AWG) and torque it into the breaker lug to the manufacturer's specification (commonly around 20 in-lbs — check the breaker label).
- Reinstall the deadfront, restore power, and test the circuit.
Tip: Always torque lugs with a calibrated screwdriver. Loose lugs are one of the most common causes of overheating and nuisance tripping.
How to spot a counterfeit
Because Eaton BR breakers are so common, counterfeits do appear, especially through unverified third-party sellers. Genuine BR130 units feature crisp molding, a clearly stamped Eaton logo, sharp printed labels, and a UL listing mark. Purchase from authorized electrical distributors or established retailers to minimize risk.
BR130 vs. closely related Eaton breakers
| Model | Poles | Amps | Typical use |
|---|---|---|---|
| BR130 | 1 | 30A | Single-pole 120V branch circuit |
| BR230 | 2 | 30A | 240V dryer, water heater, baseboard heater |
| BR120 | 1 | 20A | General-purpose 120V outlets/lighting |
| BR115 | 1 | 15A | Lighting and low-draw circuits |
| BR130AF (AFCI) | 1 | 30A | Where arc-fault protection is required |
Maintenance and lifespan
Circuit breakers are largely maintenance-free, but they aren't immortal. Eaton recommends exercising breakers (flipping them off and on) once a year to keep the mechanism free. If a breaker trips repeatedly without an obvious overload cause, feels warm to the touch, shows discoloration, or makes a buzzing sound, replace it. Most residential breakers have a useful life of 30–40 years under normal conditions.
Bottom line
The Eaton BR130 is a dependable, no-frills 30A single-pole breaker for use in Eaton BR and CH load centers. It's the correct choice when you need to restore or add a 30A single-pole circuit and you've confirmed your panel accepts Type BR breakers. For 240V appliance circuits, choose the two-pole BR230 instead. For circuits requiring arc-fault or ground-fault protection, step up to the corresponding AFCI/GFCI variant.
Frequently asked questions
Can I use a BR130 in a Square D or Siemens panel?
No. The BR130 is designed specifically for Eaton BR (and certain CH) panels. Using it in another manufacturer's panel is unsafe and violates UL listing requirements.
Can two BR130 breakers be tied together to make a 240V circuit?
Generally no. While handle ties exist, code typically requires a listed two-pole breaker (the BR230) for 240V loads to ensure simultaneous interruption of both hot legs under fault conditions. Always follow local code.
What wire size do I need with a BR130?
A 30A circuit requires a minimum of #10 AWG copper conductor. Aluminum conductors require larger sizing. Always follow NEC ampacity tables and any local amendments.
Is the BR130 AFCI or GFCI rated?
No. The standard BR130 is a thermal-magnetic breaker only. If your application requires arc-fault or ground-fault protection, choose the appropriate Eaton AFCI, GFCI, or dual-function variant.
How do I know if my panel accepts Type BR breakers?
Open the panel door and look at the label or schedule card inside. It will list approved breaker types. Eaton BR panels are clearly marked, and many older Cutler-Hammer panels also accept BR breakers.
Why does my BR130 keep tripping?
Repeated tripping usually indicates an overloaded circuit, a short circuit, or a ground fault on the connected wiring or appliance. Less commonly, the breaker itself has failed. Investigate the load first; if the breaker trips with no load connected, replace it.
