There is also ageneral linkfor protection devices, fuses, etc. I prefer Phoenix Contact, but it is not an advertising and you can choose any other vendor. You will find all the calculations there also. Personaly, I use a CB before the SITOP (or any other) power supply, and 24vdc fuses after the power supply for the circuits. Hope it helps. Feel free to ask any other questions.
