B-LINE QHCX3015H – Frequently Asked Questions
1) Is the QHCX3015H a three-pole 15 amp breaker, and what voltage is it rated for?
The Eaton/B-Line QHCX3015H is a three-pole miniature circuit breaker rated 15A at 240V. Three poles means it lands on all three phases of a three-phase panel, so it is the part for a small three-phase motor, rooftop unit, or panelboard branch circuit, not for a single-phase 120V lighting or receptacle circuit.
2) What is the interrupting rating on the QHCX3015H, and will it hold on a high fault current service?
42 kAIC. That is a high interrupting capacity for a miniature breaker, which is the whole point of the QHCX line: it lets you feed a branch circuit from a panel with a large available fault current without needing a series-rated or larger-frame device. Confirm the available fault current at your panel is at or below 42 kA at 240V.
3) Will the QHCX3015H fit the panel space I have? What are its dimensions?
Dimensions are 4.8 x 2.9 x 1 inches as listed (height, length/depth, width), and it weighs 3.4 lb. It is a QHCX type breaker, so it mounts in panelboards prepped for that Eaton type. Measure your existing breaker and confirm the panel interior is marked for QHCX before ordering.
4) Can I use this 240V three-pole breaker on a 480V system?
No. The QHCX3015H is rated 240V, so it should not be applied on a 480V or 480Y/277V system. For those you need a breaker rated for that voltage class. Keep this one on 240V three-phase panelboards.
5) Is the QHCX3015H a thermal-magnetic breaker or an electronic trip unit?
Thermal-magnetic. A bimetal handles the slow overload and a magnetic element handles the short circuit, so it rides through normal motor inrush but clears a bolted fault instantly. There is no adjustable electronic trip unit and no settings to program, which is what most MRO and contractor replacements call for.
6) Is this Eaton QC breaker UL Listed for use in a commercial building?
The QHCX3015H carries a UL Listing. For an institutional or facilities buyer standardizing on one breaker type across a building, that listing plus the 42 kAIC interrupting rating at 240V is what the electrical inspector and the panel schedule will be looking for.
7) What part number do I order to replace an existing QHCX3015H?
Order by manufacturer part number QHCX3015H. That single number carries the whole configuration: QHCX type, three-pole, 15A, 240V, thermal-magnetic, 42 kAIC. There are no finish, length, or trim options to specify with it.
