ABB Circuit Breakers

Quick Overview

Circuit breakers are essential for protecting electrical systems from overloads and short circuits. These devices, also known as circuit protectors, automatically shut off power when electrical levels become too high, preventing injury or damage to equipment. Unlike fuses, circuit breakers can be reset to restore normal operation.

Details

ABB circuit breakers are renowned for their reliability and performance across a wide range of applications. With a comprehensive selection of types, voltage, and amperage ranges, ABB has established itself as a leader in electrical protection solutions.

Types of ABB Circuit Breakers

ABB offers various circuit breakers to meet different needs:

  • Miniature Circuit Breakers (MCBs): Designed for lower current applications, these compact devices protect against overloads and short circuits. They are commonly used in residential, commercial, and institutional settings where space is limited.
  • Molded Case Circuit Breakers (MCCBs): These breakers are ideal for high-current applications and provide robust protection and reliability. ABB’s MCCBs, such as the Tmax series, feature adjustable trip settings for precise control and are widely used in industrial, commercial, and residential installations.
  • Air Circuit Breakers (ACBs): Suitable for outdoor or harsh environments, ACBs are designed to handle large power loads. They are often used in heavy industrial operations where environmental conditions are challenging.

Voltage and Amperage Ranges

ABB circuit breakers are available in a wide range of voltage and amperage ratings to suit various electrical systems:

  • Voltage: From low-voltage applications of a few hundred volts to high-voltage installations exceeding tens of thousands of volts, ABB offers tailored protection solutions.
  • Amperage: Ranging from a few amperes for residential and commercial use to several thousand amperes for heavy industrial operations, ABB circuit breakers cover all requirements.

Innovations in Circuit Breaker Technology

ABB continues to lead the industry with innovations like the solid-state circuit breaker. This technology replaces traditional mechanical parts with semiconductors and advanced software, enabling faster current interruption and enhanced safety. ABB’s solid-state breakers can detect and respond to faults 100 times faster than mechanical breakers, significantly reducing the risk of arc flash and improving the reliability of energy systems.

ABB Low Voltage Circuit Breakers

ABB’s low-voltage circuit breakers, including the SACE® Tmax® series, are designed for efficiency, accuracy, and reliability in various installations, from industrial and naval applications to power generation, buildings, and data centers. These breakers ensure high performance and safe operation, with easy component replacement.

Conclusion

Whether for residential, commercial, or industrial applications, ABB circuit breakers offer unparalleled protection and reliability. Their broad range, innovative technology, and commitment to quality make ABB a trusted name in electrical engineering.
