Product FAQs

9 answers
What equipment is the Eaton QCF2020 compatible with?

This Quicklag series breaker is designed for installation in OEM control panels, standalone enclosures, and compatible Eaton Quicklag panelboards.

Can I use this breaker in a standard residential load center?

No, the QCF2020 is a cable-in/cable-out breaker meant for OEM panels, enclosures, and specific Quicklag panelboards. It lacks the plug-on or bolt-on mounting clips required for standard residential load centers.

How are electrical connections made on the QCF2020?

This breaker features a front-mounted, feed-thru design. Both the line and load connections are made using standard box lugs (cable-in/cable-out) rather than plugging onto a panel busbar.

What wire gauge is required for the box lugs on this breaker?

The box lug terminals accommodate copper or aluminum wire sizes from 14 AWG up to 4 AWG. Always verify the specific wire material and torque requirements for your application.

How does the thermal-magnetic trip function operate on this model?

The fixed thermal-magnetic mechanism provides dual protection (LI). The thermal element offers long-time delay to handle sustained overloads, while the magnetic element provides instantaneous tripping during short circuit events.

Can the trip settings on the QCF2020 be adjusted?

No, the QCF2020 features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip settings are factory calibrated and cannot be adjusted in the field.

Does this breaker support DC voltage applications?

The QCF2020 is rated exclusively for alternating current (AC) systems up to 120/240VAC. It is not listed for direct current (DC) applications.

Is there a difference between the Eaton and Cutler-Hammer QCF2020?

No. Eaton acquired Cutler-Hammer, and they manufacture this breaker under the same QCF2020 catalog number. Units branded as either Eaton or Cutler-Hammer are functionally identical and fully interchangeable.

What type of environments is the QCF2020 suitable for?

As part of the Quicklag industrial miniature circuit breaker line, it is built for commercial, OEM, and light industrial environments requiring robust feed-thru circuit protection.
