Yes, three phase CDP (Central Distribution Panels) all use breakers to distribute the three phase supply voltage to their respective loads.
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.
This seems like a question from an electrical course, and is probably best answered by referring to your course materials. It's your test question, not ours, and there won't always be someone else to ask for the answer. Earn your diploma.
if you have 200 kva so it's 160 KW then ,you need 400 A MCCB and setting at 0.9 and use cable 4c.185 mm2 if the SMDB is nearby and all this will be change according to the ambient temperature and the electrical code used in your area
An SPN MCCB is a Solid Pole Neutral Molded Case Circuit Breaker.
what is the fault in the transformer, it trips when it is charged.it is charged through the 100 amps MCCB.
A TPN MCCB is a three phase neutral molded case circuit breaker. This type of circuit breaker is commonly used in low voltage power distribution systems.

there is three difference in ACB and MCCB, 1- ACB on off operation is easy as com pair to mccb because acb having charged spring force. 2- acb having much delay time period (category A) and mccb having low time period (category B) 3- the main diffidence is that acb having high raptching capacity and mccb are low.

Basically tpn means the tripple pole + nutral protectin mbc .
ka of mccb=transformer(KVA)x100/1.732xsecondary voltagex%impedence of transformer
what is the difference between utilization category A and B of MCCB's
want to know
