B-LINE QCR2045P – Frequently Asked Questions
1) Will the Eaton QCR2045P breaker work on a 240V single-phase panel?
Yes. The QCR2045P is rated 120/240V and is a two-pole device, so it lands on both legs of a 120/240V single-phase system and feeds a 240V load such as a compressor, heater, or subfeed. It is rated 45 amps.
2) How does the Eaton QCR breaker land wire, and does it bolt to a bus?
The QCR is a cable-in/cable-out breaker, so both line and load are terminated with conductors at the breaker rather than plugging or bolting onto a panel bus. That makes it suited to enclosed, standalone, or equipment-mounted applications rather than dropping into a loadcenter stab.
3) What are the dimensions of the QCR2045P for enclosure layout?
The breaker measures 4.8 x 3 x .9 inches and weighs 3 lb. Use those figures when checking clearance and gutter space in a small enclosure or equipment cabinet.
4) Is the QCR thermal magnetic or electronic trip?
Thermal-magnetic. The thermal element handles sustained overloads with an inverse time delay, and the magnetic element trips instantly on a short circuit. There is no adjustable electronic trip unit on this breaker, so protection is fixed at the 45 amp rating.
