Cross reference, replacement.

Replacement for obsolete QMB3603T.

If the QMB panel board was built before 1961, there is no viable replacement.
If the QMB panel board after 1961, but before 1984, a QMB361T, Series D2, QMB switch may be a suitable replacement. The QMB361T requires 4.5" of panel mounting space and will require a QMB306LEX Plug-On Extension Assembly IF the existing panel is a 38" wide QW panel board or a free standing switchboard.
