Product FAQs
6 answersWhat wire sizes are compatible with the QCF3030H circuit breaker?
The standard box lug terminals on this breaker accept wire gauges from 14 AWG to 4 AWG.
How is the Eaton QCF3030H breaker mounted?
It is designed for front-mount, through-the-door installations. It features a cable-in/cable-out feed-thru connection rather than plugging into a panelboard busbar.
Can the QCF3030H be mounted on a standard DIN rail?
No. The QCF series is specifically designed for front-mounting. If your enclosure requires a DIN rail mounted breaker, you will need the Eaton QCR series instead.
Are the trip settings on the QCF3030H adjustable?
No, this thermal magnetic breaker features fixed thermal and fixed magnetic trip settings for long-time and instantaneous protection.
What types of panels or enclosures use the QCF3030H?
This Quicklag miniature circuit breaker is designed for use in OEM control panels and industrial enclosures that require a cable-in/cable-out configuration.
Is the Eaton QCF3030H the same as the Cutler-Hammer QCF3030H?
Yes. Eaton acquired Cutler-Hammer, and they manufacture this breaker under the same QCF3030H catalog number. It is a direct replacement for older Cutler-Hammer branded units.
