How to read the numbers on a miniature circuit breaker (MCB) -
https://www.electricaltechnology.org/2015/08/how-to-read-mcb-nameplate-data-rating.html
First letter in the rating stands for the type of curve.
B curve for sensitive electronics - short circuit rating of 3-5 times the standard rated current
C curve for motors - 5-10 times
D curve for highly inductive / capacitive loads - 10-20 times.
Numerical part indicates safe current. And we should use a load 80% of this rating. Like 16A load --> 20A breaker.
Example:
C60H <-- product number
B25 <-- B curve 25A breaker.
