Product FAQs
7 answersWhat enclosures and panelboards accept the FS320030A?
This F-frame breaker is designed specifically for Eaton and Cutler-Hammer Series C panelboards, switchboards, and industrial enclosures. It will not fit in newer Series G or Power Defense panels without specific retrofit hardware.
Can the FS320030A be used in DC circuits?
Yes, in addition to standard AC applications, this breaker is rated for 250VDC systems. This makes it suitable for specific industrial DC control circuits or battery systems requiring up to a 10kA interrupting capacity.
Are the trip settings on the FS320030A adjustable?
No, this model features a fixed thermal and fixed magnetic (LI) trip unit. The overcurrent and instantaneous short-circuit protection levels are factory set for 30A and cannot be modified in the field.
What wire gauge is required for the terminal lugs?
The load side lug terminals are designed to accept wire sizes from 14 AWG up to 10 AWG. Always verify the correct torque specifications during installation to ensure a secure connection and prevent arcing.
How does this breaker mount into the panel?
The FS320030A is a unit mount breaker. It bolts directly to the panelboard bus or mounting pan, providing a secure mechanical and electrical connection for commercial and industrial applications.
What is the recommended replacement for the FS320030A?
Because the FS series is a legacy Series C component, it is frequently replaced or upgraded using the Eaton FD3030. The FD3030 shares the same 30A rating and F-frame dimensions for a direct fit.
Is the FS320030A suitable for HVAC equipment?
Yes, Eaton Series C F-frame breakers are HACR rated. This means they have been tested and approved to handle the specific inrush currents associated with heating, air conditioning, and refrigeration compressors.
