Hager mcb

[Iona222]

Seen a consumer unit hager today, was old, the mcb had a little door on it, I opened one and it had a 3a plug fuse in it. Are they for storing stuff. Whats the low down with them? Cheers.

I would like to see the look on his customers face when they open the door to him ?

You should see the look when they see my real face! ?

That does look a bit odd.

However, given the big-names involved in both doing the demo and in the rival's equipment being tested against the fuses I suspect the results must be pretty much sound.

They don't say what the MCCB or fuse is on that test, but assuming it is something like 40A then looking at a Hager 160 series MCCB the I2t is 600k while a 40A BS88 fuse is 5k.

Up at 100A the 160-series MCCB is around 1000k (250 series around 3000k) while the BS88 fuse is 70k, so it really is a big difference in let-though energy!
