Product FAQs
8 answersWhat panels are compatible with the QC1020 circuit breaker?
This breaker is intended for Eaton Quicklag panelboards and industrial control enclosures. Because it features a feed-thru (cable-in/cable-out) mounting style, it does not attach directly to a traditional load center busbar and requires wire connections on both ends.
Can I mount the Eaton QC1020 on a standard DIN rail?
Yes, but a separate mounting adapter is required. Because it is a feed-thru breaker, it will not natively snap onto a DIN rail without the corresponding Eaton adapter accessory.
What makes a feed-thru circuit breaker different from standard plug-on models?
Feed-thru breakers, also known as cable-in/cable-out breakers, utilize box lugs for both the line and load connections rather than drawing power directly from a panelboard busbar. This makes them ideal for custom control panels and standalone overcurrent protection.
Is the QC1020 suitable for switching fluorescent lighting loads?
Yes. Eaton Quicklag QC breakers in 15A and 20A configurations carry an SWD (Switching Duty) rating, meaning they are certified to safely switch 120V fluorescent lighting loads on and off.
Can this breaker be used to protect HVAC equipment?
Yes, the QC1020 is HACR rated. This indicates it has been tested and approved to handle the specific operational demands and inrush currents of heating, air conditioning, and refrigeration equipment.
Does this breaker come with the necessary wiring lugs?
Yes, line and load box lugs are included. They are designed to accept 14 AWG to 10 AWG copper or aluminum wire, allowing for flexible installation in control panels.
What safety standards does the QC1020 meet for industrial use?
This Quicklag miniature circuit breaker is UL 489 listed and CSA certified for providing branch circuit overcurrent protection.
Can I substitute an Eaton QC breaker for a QBHW breaker?
No. Although both are part of the Eaton Quicklag family, they feature different mounting configurations. The QC series is a cable-in/cable-out breaker, while the QBHW series is a bolt-on breaker designed for specific panelboard busbars.
