CAW6 series intelligent universal circuit breaker, also known as the ACB (air circuit breaker), is designed for use in AC 50Hz systems, with a rated voltage of 400V and 690V, and a rated current range of 630A to 6300A. It is used in distribution networks for the distribution of electrical energy, as well as to protect circuits and power equipment from overload, under-voltage, short circuit, and single-phase ground faults. This circuit breaker is equipped with various intelligent protection functions, enabling selective protection and precise action. Its technology is comparable to similar international products, and it features a communication interface that allows for "four remotes," meeting the requirements for control centers and automated systems. This helps to avoid unnecessary power outages and improve power supply reliability. The CAW6 ACB offers fixed and drawer-type installation methods. Importantly, this product series complies with IEC60947-2.

CAW6 Air Circuit Breakers (ACBs) are used in a variety of application scenarios due to their ability to handle high power and provide reliable protection. Here are some common applications:
Industrial Plants: ACBs are widely used in industrial settings where machinery requires high currents and protection against potential electrical faults.
Commercial Buildings: For large buildings like shopping centers, office buildings, and hotels, ACBs provide circuit protection for the electrical infrastructure that handles significant electrical loads.
Power Distribution: They are often employed in power distribution systems to protect electrical circuits from overloads and short circuits, ensuring a stable supply of electricity.
Electrical Substations: ACBs serve as protective devices within substations to control the flow of electricity and protect against faults in the grid.
Generators: ACBs are used to protect generators from damage due to electrical faults, thus ensuring the generators' longevity and reliability.
Marine Applications: Ships and offshore platforms use ACBs due to their robustness and ability to function in demanding environments, providing protection for marine electrical systems.
Data Centers: To protect the sensitive equipment in data centers from power surges and electrical faults, ACBs are an essential component of the electrical infrastructure.
Renewable Energy Systems: In renewable energy installations, such as solar parks or wind farms, ACBs protect the equipment from current overload and short-circuit conditions.
In all these scenarios, the primary role of an Air Circuit Breaker is to interrupt power in the case of an overload or a short circuit, thereby protecting the electrical system and preventing potential damage or fire hazards.
