Leviton GFCI Circuit Breaker, 1-Pole 15A, 120V
The Leviton is a branch circuit breaker with built-in ground-fault circuit interrupter (GFCI) protection, configured as a 1-Pole, 15A, 120V device with a 10KA interrupt rating. Designed as a direct replacement for standard load center positions, this breaker combines overcurrent protection with GFCI personnel protection in a single unit, helping installers meet code requirements without adding a separate device. It is also offered in 20A and 30A amperage configurations to match a range of branch circuit loads.
Key Features
- Device Type: GFCI branch circuit breaker for combined overcurrent and ground-fault protection.
- Poles: 1-Pole configuration for single-phase branch circuits.
- Amperage: Rated 15A, with 20A and 30A options also available to suit different circuit loads.
- Voltage: 120V rated for standard branch circuit applications.
- Interrupt Rating: 10KA interrupt rating for reliable fault-clearing performance.
- Ground-Fault Protection: Integrated GFCI function helps guard against shock hazards from ground faults on the protected circuit.

Leviton LB115-GF – Frequently Asked Questions
1) Does the Leviton LB115-GF breaker replace a GFCI receptacle, or do I still need one at the outlet?
The LB115-GF puts the ground-fault protection in the panel instead of at the outlet. It is a branch circuit breaker with built-in GFCI, so one device handles both overcurrent and ground-fault personnel protection for the whole circuit, and you do not need a separate GFCI device downstream to get that protection. That is the usual move for kitchen, bath, and outdoor circuits, and for cases where the first outlet on the run is hard to reach for testing.
2) What amperages does the Leviton GFCI breaker come in, and which do I use for a bathroom or kitchen circuit?
Three amperages: 15A (LB115-GF), 20A (LB120-GF), and 30A (LB130-GF), all 1-pole. A 15A handles a general 14 AWG lighting or receptacle circuit, 20A is the common choice for kitchen small-appliance and bathroom receptacle circuits on 12 AWG, and 30A covers a larger dedicated load. Size the breaker to the conductor and the load on the drawing, not the other way round.
3) Will this Leviton GFCI breaker fit my existing panel?
It is built as a direct replacement for standard load center positions in a 1-pole space, and it is a 120V single-phase branch device. Breakers are panel-specific by design, so match it to a Leviton load center. If your panelboard is another manufacturer's, use a breaker listed for that panel rather than forcing a fit.
4) Can I use this Leviton breaker on a 240V two-pole circuit like a water heater or dryer?
No. It is a 1-pole, 120V device and only protects a single-phase 120V branch circuit. A 240V load needs a two-pole breaker, and if that load also requires ground-fault protection you need a two-pole GFCI breaker.
5) Is the Square D Multi9 C60 1-pole breaker a substitute for the Leviton LB115-GF?
No. The Leviton LB115-GF is a 1-pole 15A 120V branch breaker with GFCI ground-fault protection built in, so it provides both overcurrent and personnel shock protection in one load center position. The Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC and provides overcurrent protection only. If the circuit needs ground-fault protection, the C60 would have to be paired with a separate GFCI device; the Leviton handles it in the breaker.
6) Can I use the ABB ST200M miniature circuit breaker in place of the Leviton LB120-GF?
They serve different roles. The Leviton LB120-GF is a 20A GFCI branch circuit breaker for load center branch circuit protection. The ABB ST200M is a UL1077 miniature circuit breaker, which is a supplementary protection standard rather than branch circuit protection, and it carries no ground-fault function. For a kitchen, bath, or outdoor branch circuit requiring GFCI, the Leviton is the device that fills that position.
7) Is a GFCI breaker the right choice, or should I use a standard thermal magnetic breaker?
Use the Leviton GFCI breaker where the circuit needs ground-fault personnel protection at the panel: kitchen, bath, outdoor, garage, and similar receptacle circuits. If the circuit only needs overcurrent protection, a plain thermal magnetic breaker is the simpler part, and for equipment and industrial panel work ZenSupply carries molded case and miniature types such as the Square D PowerPacT B thermal magnetic breaker and the ABB E150 Series 3-pole thermal magnetic breaker. Those are not GFCI devices and will not satisfy a ground-fault requirement.
8) I'm standardizing GFCI protection across a building. Can I spec the same breaker family for every circuit?
Across 120V single-phase branch circuits, yes. The same Leviton GFCI breaker family covers 15A, 20A, and 30A on a 1-pole footprint with a common 10kA interrupt rating, so you can hold one product line across panels and stock one style of spare. Order part numbers by amperage: LB115-GF, LB120-GF, LB130-GF.
9) What should I use for a 3-phase feeder instead of the Leviton GFCI breaker?
The Leviton GFCI breaker is a 1-pole device for single-phase 120V branch circuits, with a 10 kA short circuit current rating. For 3-phase feeder duty, the comparable molded case options include the ABB A2N Series 3-pole molded case breaker in the A2 Series, the ABB E150 Series 3-pole thermal magnetic breaker, and the Square D PowerPacT B thermal magnetic breaker. These are frame-style breakers for feeder and equipment protection rather than GFCI personnel protection.
10) How does the Leviton GFCI breaker compare to a PowerPacT Q I-Line breaker for a panelboard job?
They sit at different points in the panel. The Leviton is a 1-pole 15A 120V GFCI branch breaker weighing about 0.42 pounds and installed in a standard load center branch position. The Square D PowerPacT Q is an I-Line circuit breaker, a bolt-on style unit for I-Line panelboard mains and feeders. Use the PowerPacT Q for the distribution side and the Leviton where a branch circuit needs combined overcurrent and ground-fault protection.
11) How heavy is the Leviton GFCI breaker, and where is it made?
Each breaker weighs 0.42 pounds and is made in Mexico. Useful if you are pulling a pallet quantity for a multi-family panel upgrade or filing country-of-origin paperwork on a government or institutional order.
