Zs Values for BUSSMANN - ED355 FUSE BS88 355A 415VAC

[JWELLS23]

Hi All,

Can anyone help with calculating a Zs value for the fuse described in the title.

The fuse sizes in Fig 3A3(c) of the 18th edition wiring regulations do not have a 355A fuse and jumps from 315A fuse to 400A fuse.

I've searched and searched but struggling to find an answer.

Any help is appreciated.

Thankyou, Jord.

If you go here and download the pdf datasheet link there's a time/current curve there.
