Designed for standalone mounting, the Eaton FD1030L is a 30-amp, single-pole molded case circuit breaker. This Series C F-Frame device provides essential thermal-magnetic protection for industrial environments. Unlike standard bolt-on models, this unit-mount breaker includes both line and load side lugs for flexible feed-thru wiring. It installs into Eaton Series C switchboards, motor control centers, and individual enclosures. The breaker boasts a robust 35kAIC interrupt rating at 277VAC.
Can I use the Eaton FD1030L to replace an older Westinghouse FD1030L?
Yes. Eaton acquired the Westinghouse distribution equipment division and continues to manufacture Series C F-Frame breakers to the exact same physical and electrical specifications. The Eaton FD1030L is a direct replacement for the legacy Westinghouse version.
What does the L suffix in the FD1030L catalog number indicate?
The L signifies that the breaker is factory-supplied with both line and load side lugs. This configuration is required for feed-thru wiring in unit mount applications.
Is the FD1030L a bolt-on or plug-in breaker?
The FD1030L is a unit mount breaker. It is designed to be hardwired via its feed-thru lugs and bolted to a backpan or mounting plate, rather than plugging directly into a panelboard busbar.
Does the FD1030L mount to a DIN rail?
No. The FD1030L is a unit mount breaker designed to be bolted directly to a backpan or installed in specific Eaton Series C enclosures and panelboards. It is not compatible with DIN rail mounting.
Can this 1-pole breaker be used in a 3-phase system?
Yes, as a 1-pole breaker, it can be used to protect a single phase of a 3-phase system, provided the line-to-neutral voltage does not exceed the breaker's 277VAC or 347VAC maximum ratings.

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.
