The Eaton FD1030 is a single-pole, 30-amp molded case circuit breaker designed for commercial and industrial distribution. Belonging to the Series C F-Frame family, it provides dependable thermal-magnetic protection. This bolt-on MCCB installs into Eaton panelboards, switchboards, and motor control centers. It comes equipped with load-side lugs and serves as a replacement for older Cutler-Hammer models. Rated for 35kAIC at 277VAC, it features a non-interchangeable trip unit and is HACR rated.
Can the FD1030 replace an EHD1030 or FDB1030 circuit breaker?
Yes. The FD1030 shares the same physical dimensions and mounting footprint as other Series C F-frame breakers. It can directly replace EHD1030 and FDB1030 models, offering a higher interrupting capacity of 35kAIC at 277VAC.
Which panelboards are compatible with the FD1030 breaker?
This bolt-on MCCB is designed for use in Eaton Series C panelboards, including PRL1a, PRL2a, PRL3a, and PRL4, as well as compatible switchboards and motor control centers. It will not fit standard residential load centers.
Is this breaker suitable for direct current (DC) applications?
Yes. The FD1030 is rated for DC systems up to 125VDC, providing a 10kA interrupting capacity. It can be used in both ungrounded and grounded DC circuits.
Are the trip settings on the FD1030 adjustable?
No. This breaker features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings. Applications requiring adjustable trip curves must use an electronic trip unit like the FDE frame.
Can the FD1030 be reverse fed?
Yes. Standard thermal-magnetic Series C F-frame breakers like the FD1030 can be reverse fed, allowing power to be supplied to either the top or bottom terminals.
Is the FD1030 HACR rated for HVAC applications?
Yes. This breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific protection standard.

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.
