What are the catalog numbers for the MDGF module and sensor for NW and MTZ?

Issue:
What is the catalog number for the Modified Differential Ground Fault interface module and the MDGF sensors?

Product Line:
Circuit Breakers

Resolution:
The MDGF / SGR module is cat.# LV848891SP.  It is backward compatible with the obsolete MDGF module, S48891.
The old module S48891 is not forward compatible and cannot be used with the MTZ breaker.

This means that the newer LV848891SP for MTZ will also work with Masterpact NW breakers.
The old module S48891 cannot be used with the MTZ breaker.

If you have a mix of NW and MTZ breakers you must use LV848891SP with the MTZ but can use the existing S48891 modules with the NW breaker(s).
