What deffirent between the 100amp 3 phase and 150 amp 600v

I moved this to the correct forum.

The difference between a 100 amp service and a 150 amp service is 50 amps additional capacity on the 150 amp service. I am sure you knew that already, and I assume both are 3 phase 600 volt.

Does this answer your question, if not get back with more details.

What is the difference in what respect? Capacity? Price?

Your question cannot be answered as it is asked.
Also, why are you asking this?
