What is the Difference Between MCCB & ACB & VCB
Answer Posted / navneet kumar
MCCB"Moulded Case Circuit Breaker" is based on expension of
bimetalic strip due to thermoelectric effect.
In ACB "Air circuit breaker" two contact seperate by the
force of spring in air.
In VCB "Vaccum Circuit Breaker" two contact seperate by
force of spring in Vaccum.
However, The application of all MCCB, ACB and VCB are same
i.e. to isolate the faulty circuit from healthy one.

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
