Thread: Circuit breaker and fuses
Threaded View

Hey Everyone,
Hopefully this is a relatively simple question.
Firstly, it may be important to know that I'm building a motion control video rig, not a CNC machine.
Inside my control box I'll have some drivers of very different sizes. As such, it was suggested to me to use circuit breaker / MCBs to ensure I protect the smaller drivers. My original plan was to have an IEC socket with a switch and fuse but now I need to figure out what MCBs to get. Apologies but I'm still quite new to this.
These are the larger drivers:
2 phase large driver 1 x DM2282T
3 phase large driver 1 x DM2283T
They have built in PSU's. I'll then have 4 smaller drivers:
4 x DM542T
They will be powered by this 350W 48V PSU
Two questions:
1) Power is coming to the control box from the mains and plugging into an IEC socket which has a fuse. Should I still use that fuse if I'm adding MCBs?
2) What size MCBs do I need?
Thanks for any help.
