B-LINE QBHW2070 – Frequently Asked Questions

1) Will the B-Line Quicklag QBHW2070 breaker snap into a plug-on panel?
No. The QBHW2070 is a bolt-on breaker, so it fastens to the panel bus with screws and requires a panelboard with bolt-on mounting provisions. If your interior is built for plug-on (snap-in) breakers, this one will not seat and you need a plug-on type instead.
2) Can I use this 70A two-pole breaker to feed a rooftop AC unit or heat pump?
Yes. The QBHW2070 is HACR rated, which is what lets a breaker serve as branch circuit protection for multi-motor heating, air conditioning and refrigeration equipment. It is a two-pole, 70A device at 120/240V, so it suits a 240V single-phase condensing unit whose nameplate calls for a maximum 70A HACR breaker.
3) Can the trip unit on the Quicklag QBHW2070 be changed to a different amp rating later?
No. The trip is non-interchangeable, so the 70A rating is fixed for the life of the breaker. If the load changes, you replace the whole breaker with a different amperage in the same QBHW frame rather than swapping a trip unit.
4) Is the B-Line Quicklag QBHW2070 approved for use in Canada?
It is CSA Certified, so it is acceptable for Canadian installations subject to your local authority having jurisdiction. Ratings stay the same either side of the border: two-pole, 70A, 22 kAIC at 120/240V.
5) What exact part number do I order for a 70A two-pole Quicklag bolt-on breaker?
Order B-Line catalog number QBHW2070. The QBHW designation is the breaker type, the 2 is two-pole and the 070 is the 70A rating, so matching breakers in the same panel follow the same pattern at other amperages.
6) Is this breaker a thermal-magnetic or electronic trip unit?
Thermal-magnetic. The Quicklag QBHW2070 uses a bimetal element for overload and a magnetic element for short circuit, with a fixed non-interchangeable 70A trip. There is no electronic trip unit and no adjustable settings to program.
