Availability, replacement parts.
There is no fusible switch replacement for a QMB3640 400A QMB Series 4 switch. The replacement for this would be a QMB3400LA circuit breaker unit and a QMB310EX plug-on extension assembly. When replacing the QMB3640 you will need one QW1BL and one QW3BL filler plate. However, these old blank fillers are obsolete, no longer available, with no replacement. Suggest installer to have fabrication done at a local sheet metal shop.
