MCBs are miniature circuit breakers with optimum protection
facilities of overcurrent only.These are manufactured for
fault level of up to 10KA only with operating current range
of 0.5 to 63 Amps (the ranges are fixed), single,double and
three pole verson.These are used for smaller loads
-electronic circuits,house wiring etc.
MCCBs are Moulded case Circuit breakers,with protection
facilities of overcurrent, earth fault.it has a variable
range of 50% to 100% operating current.They can be wired for
remote as well as local operation both.They are manufactured
for fault levels of 16KA to 50KA and operating current range
of 25A to 630Amps.They are used for aplication related with
larger power flow requirement.
