The following article provides a review of prominent circuit breaker manufacturers.
ABB is at the forefront of circuit breaker manufacturers, offering homes and industries the ability to achieve maximum performance while limiting the negative impact on the environment. With companies operating in over 100 countries around the globe, ABB is a leader in its field. ABB offers products from miniature circuit breakers to molded-case breakers and guarantees its products are among the safest and most dependable on the market.
Sometimes better known for home appliances and products for various industries, Siemens is also a leading circuit breaker manufacturer. In 1998, Siemens executed a major recall of one of their circuit breaker products. The breaker in question was mostly used in hot tubs and spas. Although Siemens claims that they are unaware of any injuries due to malfunction, they erred on the side of caution. The breakers were found to have the potential cause electrocution of people in hot tubs.
GE circuit breakers are probably some of the best-known and used circuit breakers on the market. GE offers circuit breakers that are compliant with Federal regulations. This circuit breaker manufacturer offers a wide range of products for all voltage needs. From home to industrial electrical necessities, GE has products for both low and high voltage electrical outputs.
ITE is credited as the founder of 5 kV air magnetic circuit breakers. They were among the first circuit breaker manufacturers to offer low energy and high quality solutions to industrial electrical needs. ITE also offers medium and high voltage circuit breakers for a variety of purposes.
Cutler-Hammer (Eaton) is also a well-known circuit breaker manufacturer. Perhaps one of the most innovative technologies to come from this company in recent years is the fireguard circuit breaker. Cutler-Hammer's FireGuard provides protection from fire hazards that result from arcing faults. FireGuard circuit breakers will likely become the standard circuit breakers used in 21st century homes because they provide advanced protection against some of the most common causes of house fires.
The reliability of Federal Pacific, an established circuit breaker manufacturer, is questionable at best. These breakers have a notorious reputation for failure to trip when hit with a power surge. Some experts claim the rate to be upwards of 25%. Failure to trip during a power surge can cause structural fires. Rumors have circulated that the company was "de-listed" from the UL, despite the company states that they simply "went out of business". Regardless of the actual reason for this, most electrical experts recommend discontinuing the use of these circuit breakers since most tests show an unacceptable failure rate.
Another circuit breaker manufacturer, Square D, has a long history in the circuit breaker business. This company was the first to offer plug-in type circuit breakers in 1951, which was then highly innovative technology. Since that time, Square D continues to be a leader in circuit breaker technology and offers a wide variety of products for both home and industry.
According to product reviews, ETA is the leading manufacturer of circuit breakers around the world. Their circuit breakers are crafted with precision and are used for a variety of circuit protection technologies. Thermal, magnetic, high-performance and electronic are just a few of ETA's specialties. They continue to strive to create and produce the best circuit protection on the market.
Since 1947, Westinghouse circuit breakers have been among the most durable and reliable on the market. In tests, these breakers continue to deliver high performance to industries and their electrical needs. It is likely that Westinghouse will continue to be a leader in this field because they continue to meet the needs of advancing technologies.
