SQUARE D
SQUARE D QOB115GFI circuit breaker 15A 1 pole 120V AC
Ground-fault protection for a single 15 A, 120 V circuit in QO and NQ load centres with a 10 kA interrupting rating
- Ground-fault protection for 120 V circuits with 10 kA interrupting rating
- 15 A single-pole rating matches standard branch-circuit loads
- Bolt-on mounting fits QO and NQ panelboards directly
- Pressure-plate terminals accept wire without special tools

Square D QOB115GFI 15 A GFCI breaker
The Square D QOB115GFI is a single-pole ground-fault circuit interrupter rated at 15 A and 120 V AC. It mounts by bolt-on connection and uses a pressure-plate terminal for wire attachment. The paddle actuator provides manual switching in a compact 4.1 in by .8 in frame.
Suits QO load centres needing 15 A ground-fault
Electricians wiring a 15 A branch circuit in a compatible QO or NQ panel will find this breaker fits the 100 A frame size and delivers a 10 kA interrupting rating at 120 V AC. Installations that require a two-pole breaker or a higher amperage rating cannot use this model.
15 A single-pole rating at 120 V AC
The 15 ampere, single-pole, 120 V AC rating is the primary specification that determines whether this breaker matches the circuit design. Verify the panel series and required interrupting capacity before selecting this device.

Questions about this item
How do I bolt the QOB115GFI into a QO load center, and what torque should I apply to the pressure-plate terminals?
Mount the breaker by bolting it onto the bus stab of a compatible QO or NQ panelboard, then tighten each pressure-plate terminal to the manufacturer's specified torque value.
What part of the QOB115GFI will need replacement after repeated ground-fault trips?
The breaker itself is a non-serviceable unit; after it has interrupted a ground fault it should be reset, but if it no longer holds or trips without cause the entire device must be replaced.
At what fault current does the QOB115GFI reach its interrupting limit?
The breaker is rated to safely interrupt up to 10kA at 120V AC; fault currents above that level exceed its tested capacity.
