Product FAQs
8 answersHow do I connect wiring to the QCF3015H breaker?
The QCF3015H is a feed-thru (cable-in/cable-out) breaker. It uses standard box lugs that accept 14 to 4 AWG wire, allowing you to connect line and load cables directly to the breaker without needing a plug-on or bolt-on busbar connection.
What type of panels or enclosures are compatible with the QCF3015H?
This breaker is designed for Eaton Quicklag panelboards, OEM control panels, and standalone enclosures. Because it is a feed-thru breaker, it does not require a specific busbar design and can be front-mounted or DIN rail mounted in custom control panels.
How is the QCF3015H physically secured in a control panel?
The breaker features threaded steel inserts that allow for secure front-panel mounting using standard screws. This design allows the box lug terminals to be accessed from the rear, meaning cables can be connected or disconnected without removing the breaker from the front cover.
Can I use the Eaton QCF3015H to replace an older Cutler-Hammer breaker?
Yes. Eaton acquired Cutler-Hammer, and they manufacture the Quicklag series under the same QCF catalog numbers. The Eaton QCF3015H is a direct, exact replacement for a Cutler-Hammer QCF3015H.
What does the thermal-magnetic trip mechanism in the QCF3015H protect against?
The fixed thermal-magnetic (LI) trip unit provides two types of protection. The thermal element (Long-Time) protects against gradual overloads, while the magnetic element (Instantaneous) trips immediately in the event of a short circuit.
Can the QCF3015H be used in space-constrained industrial applications?
Yes. The Quicklag QCF series is designed as a compact industrial miniature circuit breaker. Its front-mounted, cable-in/cable-out design makes it ideal for OEM control panels and machinery where traditional busbar panelboards will not fit.
Is the QCF3015H suitable for 3-phase electrical systems?
Yes, this is a 3-pole breaker designed to protect 3-phase circuits up to 240V AC. It provides steel frame calibration and arc chutes in every pole for reliable industrial protection.
Is the 10kAIC rating of the QCF3015H sufficient for my application?
The 10kAIC (10,000 Amps Interrupting Capacity) rating is standard for many 240V AC branch circuits and control panels. However, you must verify that the available fault current at your installation point does not exceed 10,000 amps to ensure safe operation.
