Air Circuit Breaker (ACB)

Air Circuit Breakers (ACBs) are essential for managing and protecting power distribution systems in large-scale industrial, commercial, and utility installations. Designed to handle significant fault currents and provide dependable switching capabilities, our ACBs ensure the integrity and continuous operation of critical electrical infrastructure. These devices are built to comply with IEC60947-2, a standard that underscores their suitability for demanding international applications across Asia, Europe, South America, Africa, and Oceania.

Our ACB models feature a wide frame current coverage from 2000A to 6300A, with rated currents available from 630A to 6300A. They are engineered for a rated operating voltage of AC400 and AC690 at a frequency of 50Hz, making them versatile for various power grid requirements. With a rated insulation voltage of 1000V and a rated impulse withstand voltage of 12kV, these breakers offer enhanced safety and durability. The rapid total breaking time of less than or equal to 30 milliseconds ensures swift fault isolation, minimizing potential damage to connected equipment and reducing downtime.

Available in both 3-pole and 4-pole configurations, our Air Circuit Breakers can be specified for fixed or drawer-type installations, depending on specific system requirements and maintenance protocols. This flexibility allows for seamless integration into diverse panel designs and operational environments. Our commitment to quality is reflected in certifications such as CE, CB, RoHS, and adherence to IEC standards, providing assurance of performance and compliance for professional engineers, panel builders, and procurement managers seeking reliable electrical protection solutions.
