MCCB is actually the need to understand MCB is clear to most of the users.
MCB is for low current interruptions and has fixed current rating for trip. It will not trip at earth fault. It has low KA rating, it is suitable for simple over current application, less than 100 Aand has low cost.
MCCB (Molded case C.B) is for high current application normally above 100 A and also programmable/adjustable for earth fault, over/under voltage protections etc. It has high KA ratings,hence costly.

What is difference between TPN Mccb and 4P Mccb?
Basically tpn means the tripple pole + nutral protectin mbc .
What is the difference between Sub Main Distribution Board and distribution board?

What is the difference between a tpn mccb and a 4 pole mccb?
The difference between a tpn mccb and a 4 pole mccb is rather negligible. The only real difference is that a 4 pole mccb works a little bit faster and allows for a strong network connection. The connection with a 4 pole mccb is just a bit more reliable.
What is a mcb and what is it used for?
mcb is master circuit breaker. it is used in the circuit for the protection of equipments from over voltage.
What is the difference between MCB and MCCB?
MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation. Breakers illustrated above are in this category.MCCB (Molded Case Circuit Breaker)-rated current up to 2500 A. Thermal or thermal-magnetic operation. Trip current may be adjustable in larger ratings. MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation.

What is pillars?
feeder pillars are used for distribution of electrical supply to customer in which having a such arrangement that the Incomer with Protection (MCB, SFU,MCCB) from this protection the O/G is connected to the Bus bar and from bus bar the O/G are provided to customer,
What is SPN MCCB?
An SPN MCCB is a Solid Pole Neutral Molded Case Circuit Breaker.
Which is better TPN or 4P MCB?
TPN is same as 4P MCB TPN means Three Pole and Neutral - four pole MCB. 4P is four pole MCB
How the ka rating of mccb is calculated?
ka of mccb=transformer(KVA)x100/1.732xsecondary voltagex%impedence of transformer
