What is the impact of MCCB & MPCB on Distributed Control
System?
Answers were Sorted based on User's Feedback
Answer / kasi
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.

Answer / manish rane
MCCB is Molded case circuit breaker & MPCB is Motor
protection circuit breaker; Remote operation is major
advantage of both.
However MCCB is use for protection of distribution system &
MPCB is use for INDUCTION MOTOR for protection including
overload ,short circuit protection

Answer / pyobik
MCCB or the Molded case circuit breaker & MPCB or Motor
protection circuit breaker; their effect on the distributed
control system is that they are remotely accessible from
the control room, they can either be switched on or trip
from the control room itself.
