MCB stands for “Miniature Circuit Breaker”.
Rated current under 100 amps.
Interrupting rating of under 18,000 amps
trip characteristics may not be adjusted
Suitable for low current circuits (low energy requirement), i.e.
Generally, used where normal current is less than 100 Amps.
MCBB stands for “Molded Case Circuit Breaker”.
Rated current in the range of 10-2500 amps.
Thermal operated for overload and & Magnetic operation for instant trip in SC (Short circuit conditions)
Interrupting rating can be around 10k – 200k amps.
Suitable for high power rating and high energy i.e. commercial and industrial use.
Generally, used where normal current is more than 100 Amps.
Difference between I
in term of Circuit Breakers.
= Service Braking Capacity (means, Circuit breaker can remove the fault, but it may not be usable afterwards.)
= Ultimate Braking Capacity (means, Circuit breaker can remove the fault and remain usable)
