Anybody know where the chart for a BSEN 60947-2 Btype mcb are in the BRB?

Hi mate.

You wont find MCCB's in ol'red.

You have to contact the manufacturer direct i.e schneider MEM etc.

As some of these devices are adjustable i.e thermal and magnetic tripping characteristics.

If you do ring schneider then they weill give you all the values over the phone.

Its Hagar

I am assuming they all change with Manufactures specs?

 

[Guest123]

I would say so.

Each manufacturer will quote a different value for their devices.

I just been through the Hager technical and couldn't find owt.

Best give em a ring.

Don't forget, you use 5 second disconnection times.

still need the Time current curve trix as from that i can work out the Min Main earth allowed for install. I need the actuall disconnection time for the ZS and PFC at cable head.
