New Frankfurt International airport features has two operating passenger terminals. Terminal 1 is divided into concourses A, B, C and Z and has a capacity of approximately 50 million passengers per year. Terminal 2, which has a capacity of 15 million passengers a year, was opened in 1994 and is divided into concourses D and E.
Circuit Breaker Compatibility Guide: What Breakers Are Interchangeable
While you likely won’t have trouble finding a Homeline breaker to replace your old one, it’s very inconvenient if you do. However, despite being compatible with so many different breakers, it’s always vital to read your model numbers and labels and ensure they match up. Replacing an Eaton breaker with another brand with a mismatching model number is a recipe for disaster, and you should never do this. It’s probably a good thing then that Eaton bought out Cutler-Hammer in 1978. As a result, all Eaton and Cutler-Hammer products are made the same and compatible. Keep in mind that Cutler Hammer breakers are still available; there are fewer worldwide.
Square D is the first brand I would recommend, thanks to its sturdy construction, reliability, and ease of working with. Square D is one of the more popular breaker brands available almost everywhere. This article aims to comprehensively list which circuit breaker brands are interchangeable with others. Before making a swap, however, there are certain things you should check for regardless of what this list or any other might tell you. The first thing you need to understand about circuit breakers is that they differ depending on the brand.
Always Check for UL Certification
While Homeline breakers are interchangeable with many different breaker brands, the feeling isn’t likewise reciprocated. The lack of reciprocation is because Homeline panels have a small protrusion on their bus bars, making other breakers incompatible with them. You can only use Homeline and select Square D breakers in a Homeline panel box.
As you can see, many options exist for replacing your Challenger breaker. However, you can only use Cutler-Hammer or Eaton breakers in Challenger panel boxes and not be at fault for a code violation. While these other breakers will work, there’s a good chance they will violate your local building code or void the warranty on your panel box.

While several brands of circuit breakers are interchangeable with one another, most of them aren’t. Many different manufacturers make breakers and panel boxes, and they all put their own unique twist on the designs. As a result, most brands of breakers can only get used with the panel box of the same brand. Because Eaton is interchangeable with so many different circuit breakers, it’s common for electricians to install Eaton panel boxes in new homes. No matter where you are in the country, there’s a good chance that you can find at least one of these options that are interchangeable with Eaton. We’ve all heard of General Electric and likely have at least one appliance or electrical device made by the company.
Cutler-Hammer is one of the oldest electrical companies in the country and has produced electrical components for over 85 years. Circuit breakers were one of their biggest products in years past, but production has steadily declined in recent decades. For this reason, Cutler-Hammer circuit breakers aren’t always readily available in all parts of the country.
What Breakers are Compatible with Eaton?
Either on the breaker itself or in the panel box, there should be a list of model numbers for each breaker. They won’t give their certification to a breaker unless they have proven firsthand that you can use it safely in other panel boxes. They will also specify which panel boxes and breaker brands are interchangeable. While certain breakers from different makers may appear similar in construction or have the same load capacity, this doesn’t mean they’re interchangeable. You should always check for UL certification when using breakers interchangeably. The UL or Underwriters Laboratory goes to great lengths to test different breakers with different panel boxes.
However, like all electrical parts, circuit breakers tend to go bad and must be replaced. When that happens, it’s vital to know what kind of breaker you need and whether or not you can get a different brand than what you currently have. Aside from the BR-series from Eaton, there are very few options available to replace a Bryant breaker. Replacing a panel box is expensive work, so you should locate an acceptable replacement for the breaker if possible unless the box presents a safety hazard. UL certified means that the Underwriters Laboratory had approved the breakers for use as replacement breakers.
Double-Pole Circuit Breaker has tin-plated copper stabs to create reliable, permanent and corrosion-resistant connections. The unit has a dedicated calibration screw which is cemented to prevent shifting. Single-Pole Circuit Breaker has a dedicated calibration screw which is cemented to prevent shifting. The breaker case is made of heat-resistant thermoset for stability and structural integrity. Single-Pole Circuit Breaker has a tin-plated copper stab to create a reliable, permanent and corrosion-resistant connection. Double-Pole Circuit Breaker comes in a heat-resistant thermoset case to add stability and structural integrity to the breaker unit.
If that isn’t possible, as it often isn’t, any one of these alternative options is ok as long as the model numbers match up. You should also make sure that the construction of the new breaker is compatible with the bus bars and the construction of the Westinghouse panel box. If you can’t find a Murray circuit breaker, your best bet is to use a breaker from the company that bought them out, Siemens. Unfortunately, if Murray made your breaker box or circuit breaker before 2002, there’s no guarantee that Siemens will be compatible with it. From 2002 on, however, all Murray and Siemens circuit breakers were made the same and are compatible.
Luckily, electrical companies have caught on to the impracticality of having brands so different from one another. As a result, there are usually at least one or two circuit breaker brands interchangeable with other breakers. You must know which breakers are interchangeable, not just in appearance but also in functionality. Additionally, Westinghouse no longer makes several of its breaker models. Luckily, the company that makes Westinghouse breakers makes several other brands, as we recently discussed. As a result, Westinghouse breakers are compatible with Eaton, Cutler-Hammer, and Square D circuit breakers.
The circuit breaker features tin-plated copper stabs for corrosion resistance, creating a more reliable and permanent connection. The double-pole breaker trips to the center and contains a dedicated calibration screw which is cemented in to prevent shifting. While panel boxes and breakers often look similar, many are not interchangeable or compatible. Like all electrical devices, circuit breakers have a limited lifespan and won’t last forever. You must know your panel box’s brand and which circuit breakers are compatible with them if you don’t have easy access to an exact replacement.
