The ACB (Air Circuit Breaker) is a critical component in low-voltage power distribution systems, designed to provide reliable protection against overloads and short circuits. With its robust construction and advanced arc extinguishing technology, this circuit breaker ensures safe operation in demanding industrial environments.
Our ACB circuit breakers feature a wide current range from 200A to 6300A, making them suitable for various applications in power distribution networks. The high breaking capacity of 50-150kA ensures effective protection against short circuit faults, while the thermal stability design prevents performance degradation during prolonged operation.
The product operates efficiently in standard environmental conditions (-5°C to +40°C) at altitudes up to 2000m. Special versions are available for more demanding environments. The breaker can be installed either vertically or horizontally, providing flexibility in system design.
Key protection functions include conventional circuit breaking, circuit-breaker failure protection, overcurrent protection, overvoltage protection (OVP), and residual current circuit breaker (RCCB) functionality. These comprehensive protection features make our ACB breakers ideal for critical power distribution applications.
