MCCB-moulded case circuit breaker; ACB-Air circuit
breaker;VCB-vacuum circuit breaker.
Well they all the diff kind of design. Their operating
range is also different.

Answer / rsundareee

MCCB-moulded case circuit breaker,
ACB-Air circuit breaker,
VCB-vacuum circuit breaker,

MCCB - We can use up to 800A in low voltage side(LV)
ACB - We can use From 800A and above in low voltage side
(LV)
VCB -We can use HV side only,It is all the diff kind of
application and design

Answer / santhosh

mcb is low capcity ,acb is high,vcb control sprk high
volteg

Answer / nagaraj

MCCB is mouded case circuit breaker this is LV, 40-1600A
MCC is miniture circuit breaker this is LV, 5 to 100A
ACB it is air circuit breaker this is LV up to 800 to 6300A
VCB it is vacum circuit breaker this is HV applications
