Rated 200 kAIC at 240VAC, this 25-amp current limiting molded case circuit breaker ensures superior protection for heavy-duty commercial applications. The 3-pole design utilizes fixed thermal and magnetic trip units to quickly clear electrical faults. This unit-mount MCCB is fully compatible with Eaton Series C switchboards. It acts as an exact physical and electrical match for discontinued Westinghouse F-Frame breakers. The current-limiting architecture lowers thermal stress on components.

Product FAQs
5 answers
Are Westinghouse, Cutler-Hammer, and Eaton FCL3025 breakers interchangeable?
Yes. Eaton acquired the Westinghouse electrical distribution business and later phased out the Cutler-Hammer name. The FCL3025 catalog number refers to the exact same F-frame molded case circuit breaker across all three brand names.
What enclosures are compatible with the FCL3025 circuit breaker?
This F-frame breaker is designed for installation in Eaton Series C panelboards, switchboards, and motor control centers. It requires a bolt-on connection to the bus assembly.
What is the advantage of the current limiting design on the FCL3025?
Current limiting breakers clear short circuits extremely fast, typically in less than half a cycle. This rapid action restricts the peak let-through current and energy, providing enhanced protection for downstream conductors and equipment against severe thermal and magnetic stress.
What wire sizes are supported by the standard lugs on the FCL3025?
The factory-installed lugs accept conductors ranging from 14 AWG to 1/0 AWG. Always verify the required torque specifications printed directly on the breaker faceplate before terminating the conductors.
Is the FCL3025 suitable for systems with high available fault current?
Yes, it carries a 150kAIC rating at 480VAC and a 200kAIC rating at 240VAC. This high interrupting capacity allows safe installation in commercial and industrial facilities with substantial available short-circuit current.
