Hello kinjalpatel1899, For the CPU & IM you should use the saperate MCB, if you use the Fuse terminal then if it blow out, then you have to serach for Fuse, Which CPU you have ? based on CPU you have to Calculate the MCB rating. For IM you can 1A or 2A MCB,

Can't we use SITOP instead of MCB & Fuse ? Will it be useful ?? May I understand wrongly ? Hello, Using SITOP Power supply instead of MCB & Fuse?!!! You have to use Power Supply to feed CPU and IM. MCB or Fuse is used for protection of CPU or IM. So, I don't understand your sugesstion. Back to main question, To protect IM or CPU, we have to know the rated current consumption of each of them which varies between 0.5 A to less than 1A in many cases. You can use Fuse or MCB suitable for your load ,but please note that your load voltage is +24VDC. In case of MCB, you have to sellect the suitable characterstic. Characteristics of MCB In case of Fuse, you have to sellect the suitable fuse for semi-conductor circuits. Hope this helps.

Hello, Dear yas, Did you read the question? Thread starter was asking to use fuses or MCB for protecting CPU or IM So, I think your post is off topic. Best regards.
