Product FAQs

6 answers
What equipment is the Eaton CAH3100 designed to fit?

The CAH3100 is a legacy C-Frame molded case circuit breaker engineered for integration into older Cutler-Hammer panelboards, switchboards, and motor control centers.

What is the modern replacement for the CAH3100 circuit breaker?

When upgrading or replacing this legacy C-Frame component, the Eaton FD3100 serves as the modern crossover. The FD-frame breaker provides a form, fit, and functional replacement for older CAH-frame applications.

What does the 'H' in the CAH3100 catalog number indicate?

The 'H' designates this model as a high-interrupting capacity breaker. It provides a 22kA interrupting rating at 240VAC, offering greater fault current protection than standard CA-frame breakers.

What wire sizes are compatible with the CAH3100 lugs?

The factory-installed line and load terminals on this breaker accept either copper or aluminum conductors ranging from 6 AWG to 350 kcmil.

Can the trip curve be adjusted on the CAH3100?

No, this breaker features a non-interchangeable thermal-magnetic trip unit. Both the long-time and instantaneous (LI) trip functions are fixed and cannot be adjusted in the field.

How is the CAH3100 breaker mounted?

This is a unit-mount device, meaning it bolts directly to the bus or mounting pan of compatible Cutler-Hammer distribution equipment. It is not a plug-on or DIN-rail mounted breaker.
