To answer this question a voltage must be stated. Watts = Amps x Volts. For kilowatts divide by 1000.
TPN is same as 4P MCB TPN means Three Pole and Neutral - four pole MCB. 4P is four pole MCB
mcb is master circuit breaker. it is used in the circuit for the protection of equipments from over voltage.
MCB, Miniature Circuit Breaker is electric switch which is used to protect against short circuits
7 kw = 7000 w 7000 w / 220 v = 31,818 A Answer is 32 A MCB
it depends on the load and size of the motor if the motor has to drive heavy loads from initial state it require more torque, for this we use star-delta starters where load on motor in permissible then we use a DOL starters DOL starters are direct supply feeders to the motor so there is no rule to use a starter. we can use anything to swith the motor. for protection we need a overload relay and you ask for a 1ph motor, i.e maximum 3hp motors are available for less than 2 hp motor you can use a 6amp switch used in household or a 6amp mcb (includes overload). for 3hp a 16 amp switch or a 10amp mcb is more than enough
A 15 amp circuit breaker is used to protect a # 14 copper wire which is the minimum size wire that can be connected to a 15 amp receptacle.
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 Bank Limited was created on July 9, 1947.
32A MCB to be used
MCB = Miniature Circit Breaker CB = Circuit Breaker
mcb but cb has 2 and the other one has 3
MCB = Miniature Circuit Breaker DP = Double Pole
Many names of organization and companies are abbreviated with MCB. The most famous MCB initials are for Mauritius Commercial Bank or Muslim Council of Britain.

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.
