Description
Eaton QB3015GF is a Quicklag QB series miniature circuit breaker rated 15A, 3-pole, 3-phase and 208Y/120VAC, with a 10kAIC interrupting rating. It provides overcurrent and GFCI protection with bolt-on mounting, lug terminals and a 14-4 AWG wire range. The UL-approved breaker has a single circuit arrangement and thermal magnetic trip technology with fixed thermal and fixed magnetic adjustment, plus long-time and instantaneous trip functions. It measures 3 in wide, 3 in high and 4.25 in long. The neutral connection is not applicable.Specifications

Product FAQs
8 answersHow should I use the 15A rating when selecting this breaker?
The 15A rating is the breaker's nominal current rating, not an instantaneous trip threshold. Select it based on the circuit load and the required conductor overcurrent protection.
What protection does this breaker offer beyond overcurrent protection?
It includes GFCI protection, which detects current leaking from the intended circuit path and trips to interrupt it. This adds ground-fault protection alongside protection against overloads and short circuits.
How does the fixed thermal-magnetic trip respond to overloads and short circuits?
The thermal element provides long-time protection against sustained overloads, while the magnetic element provides instantaneous response to high fault current. Both trip elements are fixed, so select the breaker for the required protection rather than planning to adjust its trip settings.
What installation method does the bolt-on mounting require?
Bolt-on mounting requires a bolted attachment. Plan the installation around securing the breaker with that mounting method.
What conductor sizes can be connected to the lugs?
The lug terminals accept conductors from 14 AWG through 4 AWG. Choose a conductor within that range while also meeting the circuit's ampacity requirements; terminal capacity alone does not determine conductor suitability.
What dimensions should I allow for in the installation layout?
The breaker measures 3 in high, 3 in wide and 4.25 in long. Use these dimensions to plan the space occupied by the breaker in the installation layout.
What electrical system is the Eaton QB3015GF rated for?
The Eaton QB3015GF is rated 208Y/120VAC with three poles for a three-phase circuit. The Y indicates a wye-system voltage rating, so match both the voltage and system configuration when selecting the breaker.
How does the 10kAIC interrupting rating affect selection?
The 10kAIC interrupting rating describes the breaker's ability to interrupt fault current. Select it where the available fault current at the installation point does not exceed its interrupting capacity at the rated voltage.
