The circuit breaker operate when fixed and moving contacts [MALE AND FEMALE] separated in specific media.In ACB A stands for air break circuit breaker and in VCB V stands for vaccum break
circuit breaker.
Difference between vcb and acb. vcb is vacume circuit breaker acb is air circuit breaker . In vcb switching contacts fixed in vacume cylender. In acb switching contacts arranging in openly in air but other all mechanisim is same both breakers having closing coil and tripping coil and spring charge motor all are having but vcb breakers using in high voltage side to reduse the arc at on off time. But acb can use in low voltage side only.

Both circuit breakers differ from each other only in terms of arc quenching medium they are using. ACB is used for the voltage level upto 440V, whereas VCB is used beyond the 440V and can be used upto the 220KV.
Simplest practical example of ACB is the household electric switch and MCBs,

the difference lies between A and V itself
