Product FAQs
7 answersHow is the Eaton QC2090 circuit breaker mounted?
The QC2090 is a feed-thru, cable-in/cable-out breaker that panel mounts rather than plugging into or bolting onto a busbar. It can also be mounted to a standard DIN rail using a compatible Eaton adapter.
Can the QC2090 be installed on a DIN rail?
Yes, this breaker can be DIN rail mounted using the Eaton QCDINADAPT adapter bracket.
Is the QC2090 rated for use in DC circuits?
Yes, in addition to its standard AC ratings, this breaker is rated for DC applications up to 80VDC with a 5kA interrupting capacity.
Is there a difference between the Cutler-Hammer QC2090 and the Eaton QC2090?
No. Eaton acquired Cutler-Hammer, and the QC2090 is the exact same component manufactured and sold under both brand names.
How are wires connected to the QC2090 breaker?
The breaker features box lugs on both the line and load sides, accepting 4 AWG to 1/0 AWG copper or aluminum wire.
