Does Schneider Electric offer a 3-phase RCBO in the iC60 range that is compatible with Acti9 Isobar distribution boards?
Yes this can be achieved using a 3 pole iC60 breaker and then choose a vigi unit A9V02763 for 30mA or A9V06763 for 300mA and attaching these two together. When the two devices are combined to form the RCBO it will measure 6 mods ( 6 x 18mm) wide.
You can also use the 3 modules RCBOs below:
