Product FAQs
5 answersWhich Eaton panelboards accept the FS320090A breaker?
This Series C F-Frame breaker is designed for bolt-on installation in Eaton Series C panelboards, switchboards, and enclosures. It is not compatible with standard residential plug-on load centers.
Is there a direct replacement available if the FS320090A is out of stock?
Yes. The Eaton FD3090 is an exact physical substitute from the Series C F-Frame family. It shares the same dimensions and mounting but carries a higher 600V rating, making it fully backward compatible for 240V applications.
What wire sizes are supported by the standard lugs on the FS320090A?
The factory-installed line and load lugs accommodate copper or aluminum conductors ranging from 14 AWG to 1/0 AWG.
Can I adjust the trip settings on the FS320090A?
No. This breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) functions. It does not support field adjustments for the trip curve.
Can I add field-installed internal accessories to the FS320090A?
Internal accessories for Eaton Series C F-Frame breakers, such as shunt trips or auxiliary switches, must be factory installed to maintain the UL label and breaker seal. They are not listed for field installation.
