In regards to a 9070SK transformer disconnect, what is a ``F11``?

The ``F11`` optional factory modification is the suffix added to the 9070SK catalog number when the customer desires an additional fusible secondary circuit.  It is available in all 9070SK enclosures with one exception -- If the ``E23`` option is selected, then the ``F11`` option is only available in the size 2 enclosure.  See pages 12-18 and 12-19 for complete information.
