A drop-in replacement for older systems, the Eaton F3035 is a 35A, three-pole molded case circuit breaker built for commercial and industrial use. This bolt-on MCCB mounts into legacy Westinghouse panelboards, Eaton Pow-R-Line C panels, and motor control centers. It serves as an exact match for the original F3035 and is cross-referenced with modern FDB3035 substitutes. Rated for 14 kAIC at 480VAC, the unit features proven De-Ion arc extinguishing technology and is reverse feed capable.
What panelboards are compatible with the F3035 circuit breaker?
This breaker is designed for use in legacy Westinghouse panelboards, Eaton Pow-R-Line C panelboards, and compatible motor control centers that accept F-frame bolt-on breakers.
Is the Eaton F3035 the same as the Westinghouse F3035?
Yes. Eaton acquired the Westinghouse electrical distribution business, so breakers labeled under either brand with the F3035 catalog number are physically and electrically identical.
What is the modern replacement for the legacy F3035?
The Eaton Series C FDB3035 is the direct modern cross-reference and drop-in replacement for the F3035, offering the same physical dimensions and 14 kAIC rating at 480VAC.
What wire sizes do the load side lugs on this breaker accept?
The included lugs are rated to accept wire ranging from 14 AWG to 1/0 AWG.
What does the LI trip function indicate on this breaker?
The LI designation means the thermal magnetic trip unit features fixed Long-Time protection against overloads and fixed Instantaneous protection against short circuits.
Can the F3035 be used in DC power applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, with a maximum interrupting capacity of 10 kAIC.
How does this breaker mount into the panel?
The F3035 is a bolt-on molded case circuit breaker, meaning it secures directly to the panelboard busbar using bolted connections rather than snapping into place.
Is the F3035 circuit breaker reverse feed capable?
Yes, this thermal magnetic breaker is reverse feed capable, allowing it to be backfed in supported panelboards or enclosures.
