Designed for standalone industrial applications, the FD3015L delivers 15 amps of continuous current capacity with fixed thermal-magnetic trip elements. This unit-mount F-Frame breaker includes line and load lugs for installation into individual enclosures or switchboards. It replaces older Series C models. With an interrupting capacity of 35kA at 480VAC, it meets rigorous commercial standards. The breaker is HACR rated and reverse feed capable.
What does the L suffix in the FD3015L part number indicate?
The L suffix designates that the circuit breaker is supplied from the factory with both line and load side lug terminals installed.
How does the FD3015L differ from the FDB3015L and HFD3015L?
The primary difference is the short-circuit interrupting rating at 480VAC. The FDB3015L is rated for 14 kAIC, the FD3015L is rated for 35 kAIC, and the HFD3015L is rated for 65 kAIC.
Is the FD3015L compatible with older Cutler-Hammer equipment?
Yes, Eaton Series C F-frame breakers are backwards compatible with legacy Cutler-Hammer panelboards, switchboards, and motor control centers designed for F-frame devices.
What does a unit mount installation require for the FD3015L?
As a unit mount circuit breaker, the FD3015L requires a bolt-on installation. It must be secured directly to the panelboard bus or mounting pan using screws or bolts, rather than snapping onto a busbar.
Are the trip thresholds on the FD3015L adjustable?
No, this breaker is equipped with a non-interchangeable trip unit featuring fixed thermal and fixed magnetic settings. The long-time and instantaneous trip points cannot be modified in the field.
Can the FD3015L be reverse fed in a panel?
Yes, standard thermal-magnetic Series C F-frame breakers are suitable for reverse feed applications. They do not have specific line and load directional restrictions unless equipped with certain factory accessories.

175amp molded case circuit breaker
The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.
Next day shipping came quickly even though the 4th of July was coming.
I wish it came with new installations hardware but that isn’t a deal breaker.
