Product FAQs
6 answersWhat types of panels and enclosures are compatible with the Eaton QCF2030?
This Quicklag miniature circuit breaker is designed for installation in Eaton Quicklag panelboards, OEM control panels, and standalone industrial enclosures that support cable-in/cable-out configurations.
How do I connect the wiring to the QCF2030 breaker?
The breaker features a feed-thru connection type with standard box lug terminals. You will need to strip your 14 to 4 AWG conductors and secure them directly into the line and load side lugs.
Can this breaker be mounted on a DIN rail?
Yes, while it is primarily a front-mounted panel breaker, the QCF2030 supports DIN rail mounting for integration into OEM control panels and automated machinery enclosures.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the breaker's fixed thermal-magnetic trip unit provides Long-Time (L) protection against gradual overloads and Instantaneous (I) protection against sudden short circuits.
Is the Eaton QCF2030 the same as the Cutler-Hammer QCF2030?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture the Quicklag series under the Eaton brand. The QCF2030 is a direct, exact-fit replacement for older Cutler-Hammer and Westinghouse models with the same catalog number.
Does this breaker require a specific torque setting for the terminal lugs?
Yes, to prevent arcing and ensure a safe electrical connection, the box lugs must be tightened to the manufacturer's specified torque rating printed directly on the breaker's side label.
