MCCBs

richard64
Ok, no showers on this one.

Where can I find max zs and time current characteristics for mccbs.

There's nothing in the BBB covering them (as far as I can see).

Thank you.

    I'd be reasonably happy to accept a supply protected by BS 88's and then use MCCB's for the next two tier of distribution and MCB's for the final tier

     


    Absolutely agree with that (though not circuit breakers and then fuses as it causes all sorts of headaches with discrimination.....)
