B-LINE QC4070H – Frequently Asked Questions
1) How does the QC4070H terminate - is it a plug-on or a wired breaker?
Cable-in/cable-out. The QC4070H lands conductors on both the line and load side rather than plugging onto a bus stab, so plan for wire terminations at both ends when laying out the enclosure.
2) Can I use the QC4070H on a 480V industrial panel?
No. The QC4070H is rated 240V, so it cannot be applied on a 480V system. For that voltage you need a breaker rated for the higher system voltage.
3) What trip mechanism does the Eaton QC4070H use, and is it suitable for motor and general feeder loads?
It is a thermal-magnetic breaker: the thermal element handles sustained overloads and the magnetic element handles short circuits, so it rides through normal inrush while still clearing a fault fast. That is the standard trip type for general feeder and branch protection in an industrial panel.
4) Is the QC4070H circuit breaker UL Listed?
Yes, the QC4070H carries a UL Listed mark, which is what most AHJs and institutional facility specs call for on a branch or feeder breaker.
5) I need to order an exact replacement - what is the part number for the Eaton QC 70A four-pole breaker?
Order by manufacturer part number QC4070H. It is a single model, no handing or finish options to specify, so the number alone gets you the 70A four-pole QC-type thermal-magnetic device.
6) What are the dimensions and weight of the QC4070H breaker for panel layout?
The QC4070H is published at 5 in, 12 in, and .6 in for height, length/depth and width respectively, and weighs 7.31 lb. Use the height and depth figures when checking gutter space and cover clearance in the enclosure.
