HFD3045 - 45Amp Circuit Breaker Description
HFD3045 - 45Amp Circuit Breaker
When you’re replacing a circuit breaker in existing equipment, the details matter. The Eaton HFD3045 is a 45-amp, three-pole molded case circuit breaker from the Series C HFD family. It is a complete F-frame breaker with a T186 trip type, rated for 600 VAC and 250 VDC at 50/60 Hz. The HFD3045 carries an interrupting rating of 100 kAIC at 240 VAC and 65 kAIC at 480 VAC and is configured with load-side terminals. Its compact dimensions—6 inches high, 4.13 inches wide, and 3.38 inches deep—are especially useful to know when checking an existing installation for proper form and fit.

Material Compliance and Certifications
The Eaton HFD3045 is UL Listed. This gives installers and maintenance personnel a clear certification reference when checking the breaker against equipment or project requirements. No additional material-compliance certifications were included in the supplied manufacturer specifications, so those requirements should be confirmed separately when they apply to a particular installation.
Where It Works Best
The HFD3045 makes the most sense in commercial and industrial electrical systems designed around an Eaton Series C HFD, F-frame, three-pole breaker with the same electrical and physical specifications. It can be a practical choice when maintaining existing or legacy equipment where keeping the original form, fit, and function is important.
