Replacement of Fuse With MCCB
Replacement of Fuse With MCCB
(OP)
I need to replace Fuses in Control Circuit with the MCCB. The rating of Fuses are 2A 4A, 10 A.
The need to replace these fuses came as it is difficult to trouble shoot the System & change the fuse every now & then.
My question is that the Equivalent MCCB atings shall be same or diferent.

Yes. Look for miniature circuit breakers.

If we learn from our mistakes I'm getting a great education!

If short circuit level is more than 10kA then MCCB will be an option. You will also have to see the space availabilities in your panel as MCCDs are little bigger in sizes.

Thanks for your reply,
I will check the Fault level of the 480 V system.
As per my understanding(Please confirm) you are recommending if the Fault level is below 10 KA use MCB, if more than 10KA use MCCB.
I also think that the Space will not be constraint as for Phase & Neutral there are Seperate fuses, but using 2 pole MCB or MCCB the space occupied will be same.
