    Would a 4A fust be okay?
    5A would work better. Gives some safety to drives but won't trip when motrs are being worked hard.

    These are what I use, cheap and easy to wire and change.

    No don't need double pole.

    I prefer these to Din rail connectors when creating Busbars. Lot cheaper as well.
