Product FAQs

6 answers
What panelboards and equipment are compatible with the ED3110?

The ED3110 is designed for use in Eaton Series C panelboards, switchboards, and motor control centers that accept F-Frame circuit breakers.

How is the ED3110 installed in a panelboard?

It is a bolt-on circuit breaker, meaning it requires bolted connections to the panelboard bus rather than snapping or plugging into place. This ensures a secure connection in commercial and industrial environments.

What wire sizes are accepted by the standard lugs on the ED3110?

The standard lugs on this breaker accept wire gauges from 4 AWG to 4/0 AWG and are rated for both copper (Cu) and aluminum (Al) conductors.

Can the ED3110 be used in DC circuits?

Yes, this breaker is rated for 125VDC applications with an interrupting capacity of 10kAIC. This makes it suitable for specific DC control circuits or battery backup systems.

Is the ED3110 physically interchangeable with other Eaton F-Frame breakers?

Yes, the ED3110 shares the same physical dimensions and mounting footprint as other Series C F-Frame breakers, such as the FD and HFD series. However, always verify that the voltage and interrupting ratings meet your system requirements, as ED frames are rated for a maximum of 240VAC.

Does the ED3110 feature adjustable trip settings?

No, this breaker utilizes a fixed thermal and fixed magnetic (LI) trip unit. It does not have adjustable dials for long-time or instantaneous trip curves, so coordination studies must account for its fixed response.
