Leviton Dual Function AFCI/GFCI Circuit Breaker

The Leviton (LB115-DFT) is a Plug-On Mount Dual Function AFCI/GFCI Branch Circuit Breaker built to deliver combined arc-fault and ground-fault protection on a single 1-Pole, 15-Amp, 120-Volt AC branch circuit. Designed for direct plug-on installation in compatible load centers and panelboards, this breaker helps electrical contractors and maintenance electricians meet code requirements for both arc-fault circuit interruption and ground-fault circuit interruption without dedicating separate breaker slots to each protection type. Consolidating both protection functions into one 1-Pole, 15A, 120V device simplifies panel scheduling, reduces the total number of breaker positions required, and streamlines the wiring process for new construction and retrofit projects alike. It is available in AFT and DFT configuration options, allowing installers to match the specific configuration to the panel and circuit requirements on hand.

Key Features

  • Amperage: 15A rating sized for standard lighting and receptacle branch-circuit loads.
  • Poles: 1-Pole design for single-circuit branch wiring in residential and light commercial panels.
  • Voltage: 120-Volt AC rated for standard residential and light commercial branch circuits.
  • Dual Function Protection: Combines AFCI and GFCI protection in a single breaker, reducing the number of devices needed to satisfy both arc-fault and ground-fault code requirements in one panel slot.
  • Plug-On Mount: Direct plug-on mounting simplifies installation into compatible panelboards and load centers, speeding up both new installations and breaker swaps.
  • Configuration Options: Offered in AFT and DFT configurations, giving electricians flexibility to select the variant that fits the panel and circuit at hand.
  • Branch Circuit Design: Engineered specifically for branch-circuit applications where combined arc-fault and ground-fault detection is required or preferred.

Leviton LB115-AFT – Frequently Asked Questions

1) What is the difference between the Leviton LB115-AFT and LB115-DFT breakers?
They are the two configuration options of the Leviton LB115 1-pole, 15A, 120V branch breaker. Order LB115-AFT for the AFT configuration and LB115-DFT for the DFT configuration, matching the panel and circuit you are working on. Both are plug-on mount. If you are stocking for a panel schedule, specify the suffix on the order, not just LB115.
2) Can one breaker cover both the AFCI and GFCI requirement on a kitchen or laundry circuit?
That is exactly what the Leviton LB115 dual function breaker is for. It combines arc-fault and ground-fault detection in one 1-pole device, so a circuit that needs both protections takes a single panel slot instead of two devices. Typical uses are bathroom, kitchen, laundry and outdoor circuits needing GFCI plus bedroom and habitable room circuits needing AFCI.
3) Will a 15A dual function breaker handle my circuit load?
The LB115 is rated 15A at 120V AC, 1-pole, which covers standard lighting and general receptacle branch circuits wired with 14 AWG. If the circuit is a 20A run on 12 AWG, this is the wrong amperage and you need the 20A version of the breaker instead.
4) Does the Leviton LB115 mount on a DIN rail or bolt into the panel?
Neither. It is a plug-on mount breaker, so it snaps directly onto the bus of a compatible load center or panelboard. If your gear is DIN rail, look at a DIN rail breaker such as the Square D C60 UL489 miniature circuit breaker instead; if it is a bolt-on panelboard, a plug-on device will not seat.
5) Will the Leviton LB115 fit any brand of load center?
Plug-on breakers are bus-specific by manufacturer, so the LB115 is made for Leviton load centers and panelboards it is listed as compatible with. Confirm the panel brand and bus style before ordering, because a plug-on footprint from one maker will not reliably seat on another maker's bus.
6) Is the Square D Multi9 C60 1-pole breaker a substitute for the Leviton LB115 dual function AFCI/GFCI breaker?
No. The Leviton LB115 is a 1-pole, 15A, 120V branch circuit breaker that combines arc-fault and ground-fault protection in one device. The Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC, which provides overcurrent protection only. If the circuit needs AFCI or GFCI protection to pass inspection, the C60 will not satisfy it on its own - use the LB115 or add separate fault protection downstream.
7) I need a plain 15A single-pole breaker without arc-fault or ground-fault protection - what else is there?
The Leviton LB115 is specifically a dual function AFCI/GFCI device, so if you do not want the fault detection, look at a straight overcurrent breaker instead. The Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC for that role. Note the mounting difference: the Leviton LB115 is a plug-on mount breaker for load centers and panelboards, while the Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, so the panel has to accept the format.
8) My panel is DIN rail, not a plug-on load center - can I still use the Leviton LB115?
The Leviton LB115 is a plug-on mount breaker built to drop directly into compatible load centers and panelboards, so it is not intended for a DIN rail assembly. For DIN rail installations, the Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, and the ABB ST200M miniature circuit breaker is a UL1077 supplementary protector. Confirm whether your application requires a UL489 branch circuit breaker or allows a UL1077 supplementary protector before choosing between those two.
9) Can I use this breaker to feed a 240V circuit or a two-wire multiwire branch?
No. The LB115 is a single-pole device rated 120 volts AC, so it serves one 120V branch circuit only. A 240V load or a shared-neutral multiwire circuit needs a two-pole breaker.
10) Can I swap an existing standard 15A breaker for this dual function one during a panel upgrade?
That is one of the intended uses. The LB115 is a plug-on 1-pole, 15A, 120V breaker sold for panel retrofit and breaker replacement as well as new construction rough-in. The catch on any AFCI/GFCI swap is the neutral: dual function breakers need the circuit neutral landed on the breaker rather than the neutral bar, so the panel has to be one where you can separate that conductor out.
11) What should I use for a 3-phase feeder instead of the Leviton LB115?
The Leviton LB115 is a 1-pole, 120V branch circuit device and is not a feeder breaker. For 3-pole feeder and main applications, the molded case options include the ABB A2N Series 3-pole molded case circuit breaker, the ABB E150 Series 3-pole thermal magnetic breaker, and the Square D PowerPacT B thermal magnetic breaker. Those are overcurrent devices - none of them carries the combined arc-fault and ground-fault detection the Leviton provides on a branch circuit.
12) Difference between the Leviton LB115 and the ABB ST200M for protecting a control circuit?
The Leviton LB115 is a 1-pole, 15A, 120V plug-on branch circuit breaker with dual function AFCI/GFCI protection, intended for branch wiring in residential and light commercial panels. The ABB ST200M is a miniature circuit breaker built to UL1077, which is the supplementary protection standard typically used inside control panels and equipment rather than as branch circuit protection. They are not interchangeable: use the LB115 where a branch circuit breaker with fault detection is called for.
13) I-Line panel - does the Leviton LB115 fit?
No. The Leviton LB115 is a plug-on mount device for compatible load centers and panelboards, not an I-Line breaker. For I-Line panelboards, the Square D PowerPacT Q I-Line circuit breaker is the format built for that bus connection. Keep in mind the PowerPacT Q is an overcurrent device, so any arc-fault or ground-fault requirement on the branch circuits would still need to be handled separately.
