Product FAQs
8 answersWhat trip functions are included in the HFDE308035L?
This breaker is equipped with a Digitrip 310+ electronic trip unit featuring LSG protection. This provides adjustable Long-Time, Short-Time, and Ground Fault protection. The 35 suffix indicates an I2t response for the short delay and a flat response for ground fault protection.
Is the ground fault pickup adjustable on this 80A breaker?
Yes. The ground fault pickup on the 310+ LSG trip unit can be adjusted from 0.2x to 1.0x of the maximum frame rating. It also features three ground fault time delay settings: Instantaneous, 120 ms, and 300 ms.
What does the H in the HFDE308035L catalog number signify?
The H designates this as a high-interrupting capacity breaker within the F-frame family. It provides a maximum interrupting rating of 100kA at 240V AC, 65kA at 480V AC, and 25kA at 600V AC.
What wire sizes are compatible with the HFDE308035L terminals?
The L suffix in the catalog number indicates that the breaker comes with factory-installed line and load side lugs. These standard lugs accept 14 AWG to 1/0 AWG copper or aluminum conductors.
Which panelboards accept the HFDE308035L circuit breaker?
This Series C F-frame breaker is designed for installation in Eaton Pow-R-Line C panelboards, legacy Series C panelboards, switchboards, and motor control centers.
Can this Eaton breaker replace legacy Westinghouse models?
Yes. Eaton acquired the Westinghouse distribution equipment line, and current Eaton Cutler-Hammer Series C breakers are direct replacements for legacy Westinghouse Series C breakers with matching frame sizes and specifications.
Does the electronic trip unit in the HFDE308035L feature thermal memory?
Yes. The integrated electronic sensing mechanism includes a thermal memory feature that replicates the thermal heating and cooling of the load during overload conditions, preventing equipment damage from repeated overcurrent events.
Can I field-install internal accessories like auxiliary switches in this breaker?
No. For Series C F-frame breakers, internal accessories such as shunt trips, alarm switches, or auxiliary contacts must be factory-installed to maintain the breaker seal and UL label.
