ABB Circuit Breakers

ABB circuit breakers are available in various sizes and ratings to meet the needs of different applications, and are designed to protect against overloads, short circuits, and ground faults.
ABB circuit breakers feature advanced technologies such as the Tmax XT and Tmax XT2 ranges, which offer high performance and efficiency, as well as remote control and monitoring capabilities.
ABB molded case circuit breakers are typically used in industrial and commercial applications, and can handle higher currents and voltages than miniature circuit breakers. They are available in fixed and adjustable trip versions, and offer advanced features such as thermal-magnetic and electronic trip units.
ABB miniature circuit breakers are used in residential and commercial applications, and are designed to protect against overloads and short circuits. They are available in single-pole, double-pole, and three-pole configurations, and can be used in combination with a residual current device for additional protection.

FAQs
Is ABB a manufacturer of air circuit breakers?
Yes, ABB is one of the leading manufacturers of air circuit breakers (ACBs) in the world. ACBs are typically used in low voltage power distribution systems to protect against overloads, short circuits, and ground faults.
What is the current rating of ABB GFCI circuit breakers?
The current rating of ABB GFCI circuit breakers depends on the specific product and application. ABB offers GFCI circuit breakers with a range of current ratings, including 15 amps, 20 amps, 30 amps, and 50 amps.
What is a Circuit Breaker?
Magnetic Breakers
Magnetic Breakers are designed to react to short circuits or sharp spikes in voltage and current. The more current that passes through the breaker's electromagnet, the stronger the magnet becomes. When the current exceeds the rating for that particular breaker, the magnetic force becomes strong enough that it will pull the contact back and disconnect it from the other contact, disconnecting power from the device.
Thermal Protection Breakers
Thermal Protection Breakers protect against a sustained overcurrent, or a higher current, for a longer period of time. Thermal protection uses a Bimetal strip that will bend the contacts away from each other to disconnect power. Thermal Magnetic Breakers are the most common type of circuit breakers. They combine magnetic technology to protect against short circuits or sharp spikes and thermal technology that protects against sustained overcurrent for a long period of time.
