The Isobar Distribution Boards outgoing ways are designed to be fitted with only iC60H MCB's up to and including 63A.
MCB's rated at 80A and above are physically larger and do not fit the isobar busbar system.
It is possible to fit externally a NG125N breaker up to a Maximum of 100A using SEA9TB1001 (1 per phase) fitted as outgoing way and then cable into a din rail extension box (such as SEA9BNEX034N) with the NG125N fitted inside.
For more details on RCBO max current rating can be fitted in Isobar board, you can refer to this FAQ.
