Product FAQs
5 answersWhat type of panels accept the QCHW2100 breaker?
This is a Quicklag Type QC cable-in/cable-out breaker designed for unit mounting in control panels and enclosures. It does not plug into or bolt onto standard load center busbars.
Can I mount the QCHW2100 on a DIN rail?
Yes, this unit-mount breaker can be installed on a standard 35mm DIN rail, but it requires a separate Eaton DIN rail adapter, catalog number QCDINADAPT.
What is the difference between Eaton QC, QCHW, and QHCX breakers?
These prefixes indicate the interrupting rating of the Quicklag cable-in/cable-out family. The standard QC series is rated at 10kAIC, the QCHW series is rated at 22kAIC, and the QHCX series provides a 42kAIC rating.
Does this breaker require a separate line-side power feed?
Yes. As a cable-in/cable-out breaker, it requires individual wire connections for both the line and load sides, rather than drawing power directly from a panel busbar.
Is the QCHW2100 HACR rated?
Yes, Eaton Quicklag Type QC breakers from 10A to 100A are HACR rated for use with heating, air conditioning, and refrigeration equipment.
