Wylex has lunched their more compact single module arc fault detection device which contains 3 forms technology in one MCB, RCD and AFDD.
A great little device to prevent electrical fires by self-testing every 15 hours to detect arc faults on the final circuit.
Being the same size as your standard MCB it means it can be retrofitted into existing boards to give you that extra protection straight away.
