Product FAQs
8 answersWhat panels and enclosures are compatible with the HFDE322522?
This F-Frame breaker is designed for installation in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers.
What does the LSI trip function code mean on this breaker?
LSI stands for Long-Time, Short-Time, and Instantaneous trip functions. The electronic trip unit allows you to adjust these specific parameters to precisely coordinate with other protective devices in your electrical system.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed feed-thru lugs accept copper or aluminum conductors ranging from 4 AWG to 4/0 AWG.
What is the difference between the standard FDE322522 and the HFDE322522?
The H in the HFDE catalog number indicates a high-interrupting capacity. The HFDE322522 provides a 65 kAIC rating at 480VAC, while the standard FDE322522 is rated for 35 kAIC at 480VAC. Both feature the same 225A F-Frame footprint and LSI electronic trip unit.
Can the HFDE322522 be used to upgrade older thermal-magnetic breakers?
Yes, this breaker shares the standard Series C F-Frame footprint. It can directly replace older thermal-magnetic models, such as the HFD3225, when your application requires the precision of an adjustable electronic LSI trip unit.
How does the electronic trip unit improve system coordination and safety?
The adjustable Long-Time and Short-Time settings allow panel builders to shape the trip curve. This ensures that the breaker closest to a fault clears the circuit before upstream main breakers trip, isolating the issue and maintaining power to the rest of the facility.
Does this breaker support DIN rail mounting?
Yes, while it is primarily a panel mount breaker for Series C enclosures, it can also be mounted on a DIN rail using the appropriate Eaton adapter hardware.
Is the trip unit on the HFDE322522 fully adjustable?
Yes, the solid-state electronic trip unit features fully adjustable dials for the Long-Time, Short-Time, and Instantaneous pickup settings, allowing for highly customized overcurrent protection.
