TPN is same as 4P MCB TPN means Three Pole and Neutral - four pole MCB. 4P is four pole MCB
TPN MCB means Triple pole Neutral Miniature Circuit Breaker where as SPN MCB means single phase Neutral MCB.

MCB = Miniature Circit Breaker CB = Circuit Breaker
mcb but cb has 2 and the other one has 3

MCB stands for Miniature Circuit Breaker, which is a type of electrical switch that automatically disconnects a circuit in case of an overload or short circuit. DP stands for Distribution Point, which refers to a location where multiple connections from a central source are distributed to different devices or equipment.
The definition of MCB is a miniature circuit breaker, it trips if there is a line to natural fault. Ill add some extra information about the different types. RCD - residual current device = This is what you could separate you're circuits up with by inserting 1 of these in you're consumer unit (if you have lets say 10 circuits it goes like this... rcd-mcb-mcb-mcb-mcb-mcb-rcd-mcb-mcb-mcb-mcb-mcb-main switch. you see the rcd's control 5 circuits each, if 1 of these circuits had an earth fault on it, the rcd will trip and 5 of them circuits will go off, which means you have to keep tripping in you're rcd with an mcb 1 at a time to see which circuit the fault is on. RCBO - residual current breaker with overload protection- These can be installed in place of mcb's and rcd's, the rcbo is an mcb and rcd in 1 breaker. For example, i have installed a consumer unit full of these, in this case if a circuit forms a fault then its only that circuit that goes off. I hope this extra piece of information helps you along and best of luck. <<>> In electrical terminology MCB stands for Miniature Circuit Breaker.
