mcb ' miniture circuit breaker' installed at the final
distribution circuits - as close as can be to loads - in
order to protect loads

mccb ' molded case cicruit breaker' used as a main breaker
for branches . it has higher rupture capacity

acb 'air circuit breaker' used as a main breaker for the
whole network - on the head of the transformer- since it
provide releabilty for its slow opertaion

vcb ' vaccum circuit breaker' it only differs due to the
damping meduie and its used in distributors

Will transformer heating be approximately the same for resistive, inductive or capacitive loads of the same VA rating? Explain.
