Product FAQs
7 answersWhat panelboards are compatible with the EDH3175 circuit breaker?
The EDH3175 is an F-Frame breaker designed for use in Eaton Series C panelboards, including Pow-R-Line 1a, 2a, 3a, and 4, as well as compatible switchboards and motor control centers.
What is the standard lug kit for the EDH3175?
The standard lug kit for this 175A F-Frame breaker is the 3TA225FD, which accepts 4 AWG to 4/0 AWG copper or aluminum wire.
Can the EDH3175 replace an FD3175 or HFD3175 breaker?
The EDH3175 shares the same physical F-Frame dimensions and mounting footprint as the FD3175 and HFD3175. However, the EDH series is rated for a maximum of 240VAC, whereas FD and HFD breakers are rated up to 600VAC. You can only substitute the EDH3175 if your system voltage is 240VAC or lower.
Does the EDH3175 feature adjustable trip settings?
No, the EDH3175 utilizes a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory set and cannot be adjusted in the field.
Are internal accessories like shunt trips compatible with the EDH3175?
Yes, Eaton Series C F-Frame breakers support a range of field-installable internal accessories. You can add shunt trips, auxiliary switches, alarm switches, and undervoltage releases to the EDH3175.
How does the EDH3175 mount into a panelboard?
The EDH3175 is a bolt-on circuit breaker. It secures directly to the panelboard bus using specific mounting hardware kits, which must be selected based on your exact panelboard or meter stack model.
Can I use aluminum wire with the EDH3175?
Yes, the standard 3TA225FD lugs provided with this breaker are dual-rated for both copper (Cu) and aluminum (Al) conductors. Ensure you apply the appropriate joint compound when terminating aluminum wire.
