Miniature circuit breaker distribution boards
The Isobar range allows for hundreds of Distribution board combinations and can be assembled from just a few modules. Isobar 4c modules can be joined at the top, bottom or sides to make assemblies that cater for the biggest or most complex installations.
The standard range includes three-phase 250A boards with up to 24 outgoing ways and single-phase 125A boards with up to 23 outgoing ways. |

Split-load / multi-service configurations are available as part of the standard range and all units are compatible with incoming disconnectors RCCBs and MCCBs. Compatability also extends across the C60H ranges of MCBs and RCBOs for the protection of outgoing circuits.
All versions of Isobar incorporate the unique busbar connection device, which allows for a quick connection and unused ways are isolated.
