An SPN MCCB is a Solid Pole Neutral Molded Case Circuit Breaker.
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 the fault in the transformer, it trips when it is charged.it is charged through the 100 amps MCCB.

mccb
An SPN MCCB is a Solid Pole Neutral Molded Case Circuit Breaker.
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
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.
