ABB SACE Isomax S4 circuit breakers: old part numbers and replacement

Old ABB SACE Isomax S4 ordering codes and catalog numbers, as printed in ABB's own catalogs, with help finding the current ABB replacement.

Finding a current replacement

ABB's current molded case circuit breakers include the Tmax XT family. We don't hold an ABB migration guide for the Isomax S4, so we match each old Isomax S4 part to its current replacement by hand. Send us the old number on a quote request and we will confirm it.
