Schneider Electric (Square D) AC Disconnect Recall

Just an FYI,

I received this notice from my utility (PG&E) about a Square D Brand General Duty Safety Switch 30/60A, 120/240Vac, NEMA 3R recall.

Some date code/models do not open the internal knife switches when the outside handle is thrown. Apparently (reading the recall notice), if the switch does function correctly (switches open when outside handle is moved to OFF), then all is OK.

    I saw a service note on this about 2 months ago Bill. I was glad it was not the 600vdc model ;)
    This recall unit would probably be required with a grid/batteryless inverter.

    Yes, this model was used for my GT System ac disconnect. However, my system is way older than these date codes.
