B-LINE QCR2010T – Frequently Asked Questions
1) What amperage and voltage is the B-Line QCR2010T Quicklag breaker rated for?
The QCR2010T is a two-pole, 10 amp thermal-magnetic breaker rated 120/240V with a 10 kAIC interrupting rating. That interrupting rating is what has to match or exceed the available fault current at the panel, so check the 10 kAIC figure against your short-circuit study before you install it.
2) How does the QCR Quicklag breaker connect to the wiring, and does it plug onto a bus?
It doesn't plug on. The QCR2010T is a cable-in/cable-out breaker with rear mounting, so both line and load land on terminals rather than a panel bus stab. Standard terminals are box type lugs, and they also accept ring terminal connections on line and load side using the #10-32 terminal screw supplied.
3) Can I change the trip rating on a QCR Quicklag breaker later if the load grows?
No. The QCR breaker uses a non-interchangeable trip, so the 10 amp rating is fixed. If the load changes you replace the breaker with a different amp rating rather than swapping a trip unit.
4) What size is the QCR2010T breaker and how much space does it take in an enclosure?
Body dimensions are 5.2 x 3.3 x 1.2 inches, and it weighs about half a pound. Allow for the rear mounting arrangement plus lead room at both ends, since wiring enters and leaves on cable terminals rather than a bus stab.
5) Do I need to order lugs separately for a QCR Quicklag breaker?
No extra lug kit is needed for standard use. Box type lugs are the standard terminal on the breaker, and the #10-32 terminal screws for ring or spade lug connections come with it. You only need to supply the ring or spade terminals themselves if you're crimping to that style.
6) Is the QCR2010T suitable for a 240V two-wire load like a heater or small motor circuit?
Two poles at 120/240V and 10 amps covers a 240V two-wire branch circuit at that rating. It's a thermal-magnetic device, so it gives thermal overload response plus instantaneous magnetic trip on a short. Confirm the 10 kAIC interrupting rating is adequate for the fault current at that point in the system.
7) What's the exact part number to order for the 10 amp two-pole QCR Quicklag breaker?
Order B-Line part number QCR2010T. That is the Type QCR 1/2-inch Quicklag industrial thermal-magnetic breaker, two-pole, 10A, 120/240V, 10 kAIC, cable-in/cable-out with rear mounting.
