More Information about ABB Circuit Breakers

In terms of design, ABB circuit breakers often come in multiple poles to suit different system requirements. The company also offers "K curve" and "K char" options, which refer to the trip characteristics of the breaker, allowing you to fine-tune the device to your specific needs for enhanced protection.

For those interested in energy efficiency, ABB's low voltage circuit breakers are designed to reduce energy consumption while still providing reliable protection. These are particularly useful in systems where power conservation is a priority. The products are UL-listed, which means they meet strict safety standards.

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.
