Two relevant details of note here:
1. The breaker on only the 5548 model was of a "toggle switch"
configuration, rather than the push button used on the rest of the
models. If you have a push button as you describe, the problem may
be that it was an incorrect previous replacement.
2. As Ray has noted, the 4048 could out surge the 5548. They had
different firmware, giving the 5548 a tighter voltage window
during surges, resulting in less surge capacity due to less
tolerance for voltage dips under surge loads.

Try Mouser electronics. Otherwise,
I'd consider bypassing it, and have a regular breaker (30 or 40
amp) on theout put.
The tripping was probably because the breaker was
malfunctioning. Usually the SWs will trip their on board
computer to shutdown for over current, and the breaker should
never be used. The 5548s were kind of weird though. I never
liked those. I've had SW4048s out surge the 5548s hands down.

Hi all-
I'm having some difficulty finding a replacement for the
little push-button circuit breaker on an old Trace SW5548
inverter. This is located on the lower left corner of the
box, below the wiring access panel. The customer has had
repeated tripping of this breaker from overcurrent, so it
has been doing it's job. But now the button won't reset.
It's a 35 amp breaker. I have only been able to find
smaller ones in the online catalogs.
Anyone know of a better parts supplier?
Thanks
