Product FAQs
6 answersWhat equipment is the FC3020 circuit breaker designed to fit?
This legacy F-Frame breaker is a direct fit for older Westinghouse Pow-R-Line panelboards, switchboards, and motor control centers. It bolts directly to the bus, avoiding the need for aftermarket retrofit kits.
Is the FC3020 suitable for direct current (DC) applications?
Yes. While primarily used in AC systems up to 600VAC, it is also fully rated for 250VDC systems. It provides 10kAIC of interrupting capacity for DC control circuits, battery backups, or industrial DC drives.
Do I need special lugs for aluminum wiring on the FC3020?
No, the factory-installed lugs are dual-rated for both aluminum and copper conductors. They accept wire sizes from 14 AWG up to 1/0 AWG.
How does the LI trip function operate on this breaker?
The thermal-magnetic trip unit provides two levels of protection. The long-time thermal element prevents damage from sustained overloads, while the instantaneous magnetic element trips immediately during a short circuit. Both settings are fixed on this specific model.
Does this breaker snap into the panelboard?
No, the FC3020 is a unit-mount, bolt-on circuit breaker. It must be securely bolted to the panelboard bus or mounting bracket, ensuring a rigid connection suitable for industrial environments.
Can I use the FC3020 in a modern Eaton panelboard?
The FC3020 is specifically designed for legacy Westinghouse Pow-R-Line enclosures. For modern Eaton panelboards, you will typically need a current Series C or Series G breaker, unless the specific panel is explicitly cross-listed to accept legacy F-Frame breakers.
