Hello all, i have a question on selection of circuit breaker.
Can 4P 125A 16kA breaker be used in place of 4P 125A 10kA ?
I appreciate your sincere response.

Hello Rahmon:thumbsup:
I do not think so, You should use the exact same make and model number.
Thank you for the answer.
perhaps I'm not clear with " You should use the exact same make and model number"
But I like to state that what is required is 4P 125A 10kA circuit breaker, but that particular kind of breaker with such features is obsolete and I am now thinking of possible substitute.

That's a difficult question to give a "yes" or "no" answer to without more information.

Is the 10kA rated breaker you are looking to replace part of a series rated combination?

Is the available fault current at or below 10,000 amps?

Is the replacement breaker recognized for use in the equipment?

You need to know your available fault current (do you have a tester?) for both line-line and line-PE faults.
