Issue:
Product features comparison

Product Line:
Surge Protection Device 

Environment:
EMA , SSP

Cause:
Replacement

Resolution:
The new SSP devices have a smaller footprint, use screw covers instead of hinged, are Nema 1 standard now not 3R, and are Type 1 now vs. Type 1 or 2 . Both use the same MA*** modules and the modules are interchangeable.
