Product FAQs
6 answersWhat equipment is compatible with the CAH2150 circuit breaker?
This C-Frame breaker is specifically designed for installation in Eaton and Cutler-Hammer group metering stacks, tenant main applications, and Type ECC enclosures.
What is the modern replacement for the legacy CAH2150?
The CAH2150 is a legacy model. For modern upgrades, Eaton replaces this unit with the CCVH2150, which fits the same metering enclosures and provides the required interrupting capacity.
What wire sizes do the standard lugs on this breaker accept?
The factory-installed line and load lugs accommodate copper or aluminum conductors ranging from #6 AWG to 350 kcmil.
How is the CAH2150 mounted inside an enclosure?
This is a unit-mount, feed-thru circuit breaker. It bolts directly to the mounting pan or bracket inside compatible metering stacks and enclosures, rather than plugging onto a busbar.
Is the CAH2150 suitable for systems requiring high fault current protection?
Yes, this breaker features a 22kAIC interrupting rating at 240VAC, making it appropriate for tenant main and group metering applications where available fault currents exceed standard 10kAIC limits.
What type of trip mechanism does the CAH2150 utilize?
It uses a fixed thermal-magnetic trip unit, providing both long-time delay for standard overload protection and an instantaneous response for short-circuit faults.
