C vs D Curve Circuit Breakers, What’s the Difference?

I looked online to try to better understand the purpose and meaning of the different curve circuit breakers, but had no luck.  Can anyone answer what is the puruse for having different curve circuit breakers.  I"m looking for a 1 amp or less circuit breaker.  I understand I can use a fuse holder and use fuses as a component, but I thought it'll be better to use a breaker instead.  Is their a better component that's on the market instead that I may not be aware of?

The different curves indicate the instantaneous tripping current. It means the minimum value of current causes the circuit to trip without intentional time delay.

C- curves type are used for heavy currents in normal working.(e.g. Heaters, Gyesers, Irons)

D-curves types are used for heavy inrush currents.(Motors etc)
