What is the difference between Class 8940 Series A and Series B devices?

 Issue:
Trying to identify Series A or Series B, pump panels. 

Product line:
Class 8940

Environment:
all

Cause:
Replacement parts

Resolution:
Series B panels were introduced in 2008.  The solid state overload was modified to add addtional protective covers and also de-sensitized to single phasing.  This was to help with poor power qualityand power environmental conditions out in the field.

Starting in June 2013, the overload was again updated to 9065 SSOLR, series F, which is noted on the overload only.  The 8940 panels are still identified as Series B.
