ACB is used for the protection of industrial plants and electrical machines such as capacitors, generators, and transformers, etc. ACB is mainly used in plants where there is a risk of fire or explosion. ACB is also used in NGD and Electricity Sharing System.
Functions of Air Circuit Breaker are :
• It opens or closes a circuit automatically or manually.
• Open circuit automatically when a fault take place such as over current, short circuit,
earth fault, over frequency, reverse power, etc
• It dampens the arcing in case of overloading
Applications of Air Circuit Breakers are :
• ACB is used for the protection of industrial plants and electrical machines such as capacitors, generators, and transformers, etc.
• ACB is mainly used in plants where there is a risk of fire or explosion.
• ACB is also used in NGD and Electricity Sharing System
• They are also used for controlling power station auxiliaries
• Also used in Low/High Current and voltage applications
• Also used in maintaining the switchgear and indoor medium voltage.
ACB ( Air Circuit Breaker ) is an electrical device used to provide Overcurrent and short-circuit protection for electric circuits over 800 Amps to 10K Amps. These are usually used in low voltage applications below 450V. We can find these systems in Distribution Panels (below 450V).
