The Universal Air Circuit Breaker (ACB) is designed for reliable power distribution in industrial and commercial applications. With a rated operational voltage of AC400/415/690V and current range from 400A to 6300A, this breaker ensures safe and efficient electrical system protection.
Available in both fixed and withdrawable configurations, our ACB meets IEC/EC 60947-2 standards and supports multiple communication protocols including Modbus, Profibus-DP and Device Net for seamless system integration.
The breaker operates effectively in temperatures ranging from -5°C to 40°C, with special consideration for humidity conditions. Its robust design withstands altitudes up to 2000m and complies with pollution grade 3 requirements.
Key protection features include intelligent controller functionality, pole N protection capability (for 4P and 3P+N models), and comprehensive short-circuit protection with Icu ratings up to 100kA at 400V.
The mechanical service life reaches 30,000 operations for maintained units, while electrical life varies from 300 to 6,500 operations depending on model and voltage. All units feature quick operating times with disjunction completed within 23-32ms.
