Product FAQs

8 answers
What does a Feed-Thru connection mean on the QC2030?

A feed-thru, or cable-in/cable-out, connection means this breaker does not plug or bolt onto a load center busbar. Instead, it is independently panel-mounted, and both the incoming line power and outgoing load power are wired directly to the terminal box lugs on either end of the breaker.

Can the QC2030 be installed in a standard Eaton residential load center?

No. The QC series is designed for standalone installation in control panels or enclosures. It lacks the necessary mounting clips or busbar brackets required to install in standard BR, CH, or BAB style load centers.

Can the Eaton QC2030 be mounted on a DIN rail?

Yes. While it is natively a panel-mount breaker, it can be securely mounted to a standard 35mm DIN rail using an optional mounting adapter, such as Eaton catalog number QCDINADAPT.

Is the QC2030 approved for direct current (DC) circuits?

Yes, this breaker carries specific DC ratings for low-voltage applications. It provides a 5 kAIC interrupting capacity at 48VDC and a 3.8 kAIC rating at 62.5VDC.

What are the wire gauge and material requirements for this breaker?

The integrated box lugs accommodate wire sizes from 14 AWG up to 10 AWG. The terminals are rated for use with either solid or stranded copper and aluminum conductors.

What distinguishes the Quicklag QC series from Eaton's QCR and QCF series?

The QC series features a standard cable-in and cable-out panel mounting configuration. In contrast, the QCR is specifically designed for rear-mounting installations, and the QCF is built for front-mounting inside specialized enclosures.

Is this breaker suitable for protecting heating and cooling equipment?

Yes, the QC2030 carries an HACR rating. This makes it approved for providing dedicated branch circuit protection to multi-motor heating, air conditioning, and refrigeration equipment.

What does the LI trip function code indicate on this breaker?

The LI designation means the breaker utilizes a thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) protection. The Long-Time function prevents overloads by tripping slowly on moderate overcurrents, while the Instantaneous function provides immediate tripping to clear high-fault short circuits.
