How can we help you today?

Issue:
Availability of replacement parts

Product Line:
QMB panelboard, switchboard with QMB distribution

Resolution:
Replacement parts are no longer available for the QMB3240 branch switch device. We do, however, have a replacement for the complete device, if a circuit breaker is acceptable in lieu of fuses. This breaker device is catalog number QMB3400LA, and includes a 400 A, 3 pole circuit breaker.

NOTE: Along with the QMB3400LA, a plug on extension assembly, catalog number QMB310EX, will also be required. In addition, since the QMB3400LA requires only 7.5" of mounting space (as opposed to the 12" required by the QMB3240), (1) QW1BL and (1) QW3BL blanks are also required in order to fill the remaining 4.5" of mounting space after removing the QMB3240. However, these old blank fillers are obsolete without replacement. Suggest installer to have fabrication done at a local sheet metal shop. (A cut sheet for the QMB3240 is not available.) Refer to the Supplemental Digest for additional information about the QMB3400LA.
