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 applications 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.

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.
