Application: Insulation barriers IBL-400 for ABN/S403c, EBN/S403c
These allow the insulation characteristics between the phases at the connections to be increased, They are mounted from the front, even with the circuit-breaker already installed, inserting them into the corresponding slots, They are incompatible with both the insulating terminal covers, It is possible to mount the phase separating partitions between two circuit-breakers side by side
