FAQ000220707

30 September 2021

The substitution for the MDGF module part number "48891" (MasterPact NW range) is part number "LV848891SP" (MasterPact MTZ range).

While 48891 is not compatible with Masterpact MTZ, the LV848891SP is compatible with the Masterpact NW.

The only limitation is “it cannot be used to power up trip unit during testing/setup”.

The information "LV848891SP not compatible with NW breaker" in the MTZ substitution guide, as of 14/09/2021 is incorrect and will be corrected in the next version.
