Cummins power PCC technology and MCCB ?

Dear sirs,

I have one question as the following:

Cumminspower have one control call PCC ( Power command control) , is this function (protection function ...) same with MCCB or ACB.

Because my freind, that have inquiry for 1 diesel generator set for his factory, and he received quotation from Cummins power dealer ( Deithelm technology... in VN) and they mentioned that : " Cummins power's PCC technology no need to use MCCB"

If you have some advise us regarding this matter, please reply me as following address: dokomtsu@yahoo.com

Thanks
