Product FAQs

7 answers
What equipment is compatible with the EHC3100 breaker?

The EHC3100 is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers that accept F-Frame bolt-on breakers.

What is the direct replacement or cross-reference for the EHC3100?

The EHD3100 is the standard modern cross-reference for the EHC3100. Both are 100A, 3-pole, F-Frame breakers with identical physical dimensions and a 14kAIC rating at 480VAC.

What wire sizes do the standard lugs on the EHC3100 accept?

The factory load-side lugs on this breaker accommodate wire ranging from 14 AWG up to 1/0 AWG.

Is the EHC3100 rated for use in DC electrical systems?

Yes, this thermal-magnetic breaker is rated for DC applications, providing up to a 10kA interrupting capacity at 250VDC.

Are accessories interchangeable between the EHC3100 and other Series C F-Frame breakers?

Yes. Because the EHC3100 is built on the standard Eaton Series C F-Frame platform, it shares physical dimensions and accepts the same internal accessories, such as shunt trips and auxiliary switches, as EHD, FD, and HFD breakers.

How does the EHC3100 mount into the panelboard?

This is a bolt-on circuit breaker. It secures directly to the panelboard bus using bolted connections rather than snapping into place, providing a secure, vibration-resistant installation.

What type of trip functions does the EHC3100 provide?

It features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions (LI). This provides standard overload and short-circuit protection.
