Cell Key Interlocks for Masterpact NW and MTZ breakers

Issue:
What is the recommended cell key interlock for Masterpact breakers?

Resolution:
We recommend using NWCELLKEY for NAM MTZ and NW UL489 and UL1066 breakers.  Refer to attached instruction bulletin HRB28360 which comes with the kit and includes charts for the recommended combination to use for each amp and AIC rating.

Use LV83376SP for breakers in the IEC market.  The attached instruction sheet has a chart showing the possible combinations, but it doesn't tell you which breakers to put them on, so you can choose whatever combinations you wish for your job site. Proper documentation would be required onsite to document which keying configuration was used for each breaker rating.
