ABB Circuit Breakers

ABB has many different kinds of circuit breakers, which include molded case circuit breakers (MCCBs), miniature circuit breakers (MCBs), and air circuit breakers (ACBs). These types of circuit breakers are used in various automation solutions where energy efficiency is paramount. MCCBs are used in applications where a high level of performance is required because they can handle large amounts of power. The compact design of MCBs makes them suitable for use in confined spaces. ACBs work well in outdoor installations or situations where the environmental conditions are poor.

ABB's MCCB, such as the Tmax series, are developed for high-current applications and offer top-notch protection and reliability. They have an adjustable trip setting that enables precise control over the protection parameters. Many installations—industrial, commercial, and even residential—use MCCBs because they can handle a wide range of voltages and currents.

More Information about ABB Circuit Breakers

Compact MCBs such as ABB's System pro M compact series are used where the currents involved are relatively low and offer protection against overloads and short circuits as part of a circuit Protective Device strategy. They may be found in residential, commercial, or institutional buildings—anywhere there is a need for an elementary circuit Protective Device to help ensure “failure-to-safe” outcomes and trouble-free operations.

FAQs

Are ABB circuit breakers and accessories available for din rail mount?

Yes, ABB circuit breakers and accessories are available for DIN rail mounting, providing convenient and flexible installation options for various electrical applications. Details of product pricing and delivery is distributor specific.

What is an ABB breaker used for?

An ABB breaker is used for protecting electrical circuits from overloads, short circuits, and faults by automatically disconnecting power when irregularities are detected, ensuring safety and reliability in industrial, commercial, and residential applications.

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.
