Description
Engineered for industrial applications, the Eaton CAH3100 provides reliable thermal-magnetic protection. This 3-pole, 100A MCCB is part of the classic AB DE-ION series, supporting legacy distribution systems. The unit-mount design allows installation into older Cutler-Hammer panelboards and switchboards. For facilities upgrading, this C-Frame breaker is replaced by the FD3100. Operating at 240VAC, it features a 22kAIC rating and fixed LI trip functions.Specifications

Product FAQs
6 answersWhat 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.
