HFD3090L - 90Amp Circuit Breaker

HFD3090L - 90Amp Circuit Breaker

When you’re replacing a circuit breaker in existing equipment, the details matter. The Eaton HFD3090L is a 90-amp, three-pole molded case circuit breaker from the Eaton Series C HFD family, built around the F frame. It carries voltage ratings of 600 VAC and 250 VDC and operates at 50/60 Hz. For fault-current requirements, the HFD3090L is rated 100 kAIC at 240 VAC and 65 kAIC at 480 VAC. It also uses the T186 trip type and comes with line and load terminals. Those specifications are especially useful when you're trying to match an existing breaker rather than simply finding another 90A unit.

Material Compliance and Certifications

The Eaton HFD3090L is UL Listed. That makes the certification easy to identify when reviewing a breaker against the requirements of an existing electrical system or project. No additional material-compliance certifications were identified in the supplied product specifications, so any project-specific environmental or material requirements should be checked separately.

Where It Works Best

The HFD3090L makes the most sense in commercial and industrial electrical equipment designed to accept an Eaton Series C HFD F-frame molded case circuit breaker with these ratings and dimensions. It's particularly relevant for maintenance and replacement jobs where matching the existing breaker’s form, fit, and function is important.
