Further Information

This consumer board is ideal for large installations, such as a factory or large warehouse. A range of Type B MCBs are included with the board but you also have three available ways (pack of blanks included with board too). This allows you to add additional circuits later on down the line if necessary.
If you require MCBs that aren’t included with the board, remember to check out our full range of MCBs, available in both type B and type C.
