Application scope
Intelligent air circuit breaker is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current up to 6300A. It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and single-phase earthing fault.
With intelligentized and selective protection functions,intelligent Air Circuit Breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applicable for power stations,
factories, mines (for 690V) and modern high buildings, especially for the distribution system of intelligentized building.
Intelligent air circuit breakers also come with built-in smart control and real-time monitoring features. They deliver accurate protection, allow easy parameter adjustment and boast strong breaking performance. They work perfectly to maintain reliable power distribution in factories, commercial complexes, data centers, power substations and various infrastructure facilities.
