[RE-wrenches] circuit breaker for SW5548

[Tump]

I believe that that breaker is primarily used for the charging circuit of the SWs.I usually find this tripped during the charge cycle. I would verify; when the breaker trips, check the charge settings menu10 + the AC2 input settings, also check that you don't have a bad battery causing over charging. Let me know off list as I have in my truck a 30A breaker that I use as a replacement for the SWs.Tump

>> 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?
