For customers who have any Merlin Gerin ACB’s of Types ‘DA’ or Masterpact ‘M’ of any configuration in either 3 pole or 4 pole with Horizontal or Vertical connections. R&B Have the solution to retrofit these units and replace them with the current range of ACB’s from the Schneider Masterpact ‘NW’ and ‘NT’ Range of ACB’s.
We have developed the full range of rear connections to allow the replacement of any of the heritage range to the current range without the need for any on-site Busbar Modifications.
These connections are supplied along with the ACB, Cosmetic and Insulation Barriers to achieve a safe and well engineered solution to the replacement of these old types of ACB’s into existing switchboards on Marine, Offshore and Industrial Installations.
