ACB is short for "Air Circuit Breaker".Air circuit breaker is a kind of circuit breaker using air as the arc extinguishing medium, which is mainly used in high current and large capacity power system.

Here are some key features about ACB

High Rated Current

Suitable for high current applications, usually rated current above 1000A, able to handle larger capacity power loads.

High Breaking Ability

The ability to quickly disconnect the circuit in the case of short circuits and other failures to prevent equipment damage and fire and other dangerous situations.

Flexibility and Adjustability

Often with adjustable overload, short circuit and ground fault protection Settings, can be configured according to the specific power needs.

Remote Control and Monitoring

Many ACBs support remote operation and condition monitoring for automated power systems and smart grids.

Easy Maintenance

The design is usually easy to check, maintain and replace parts to ensure the reliable operation of the system.

Applications

Widely used in large industrial facilities, power substations, data centers and other large buildings and infrastructure requiring high-reliability power protection.

ACB plays a very important role in the power system, providing efficient and reliable power protection and control to ensure the safe and stable operation of the power system.
