Product FAQs
7 answers
What type of trip unit is installed in the HFDE322536?
This breaker features a Digitrip 310+ electronic trip unit. The 36 suffix in the catalog number indicates it provides LSIG (Long-Time, Short-Time, Instantaneous, and Ground Fault) protection with a flat response short delay.
Are the trip settings adjustable on the HFDE322536?
Yes, the Digitrip 310+ LSIG trip unit allows you to adjust the continuous current, short delay pickup and time, instantaneous pickup, and ground fault settings to coordinate with your specific system requirements.
Does the HFDE322536 provide ground fault equipment protection?
Yes, the integrated LSIG trip unit includes adjustable ground fault protection. The fault level pickup contains seven settings ranging from 0.2x to 1.0x of the 225A frame rating, with time delay options of Instantaneous, 120 ms, or 300 ms.
Which Eaton panelboards are compatible with the HFDE322536?
This bolt-on Series C F-frame circuit breaker is designed for installation in Eaton Pow-R-Line C panelboards, as well as compatible Eaton switchboards and motor control centers.
Does the HFDE322536 include line-side lugs?
No, standard Series C F-frame breakers with this catalog number configuration (lacking an L suffix) are supplied with load-side lugs only. The line side is designed to bolt directly to the bus in a panelboard or switchboard.
What wire sizes do the standard lugs on the HFDE322536 accept?
The factory-installed load-side lugs accept 4 AWG to 4/0 AWG copper or aluminum (Cu/Al) conductors.
What is the difference between the FDE322536, HFDE322536, and FDCE322536?
The prefix determines the interrupting rating at 480VAC. The FDE322536 is rated at 35 kAIC, the HFDE322536 is rated at 65 kAIC, and the FDCE322536 is rated at 100 kAIC. All three share the same physical dimensions and 225A LSIG trip unit.
