Leviton LB115-AF – Frequently Asked Questions

1) Does the Leviton LB115-AF AFCI breaker come in a 20 amp version?
Two amperage choices are offered on the Leviton AFCI branch breaker: 15A as the LB115-AF and 20A as the LB120-AF. Both are single-pole AFCI devices. Pick the amperage to match the branch circuit conductor you are protecting, 15A for a 14 AWG circuit and 20A for a 12 AWG circuit.
2) Is a 10kA interrupt rating enough for a residential load center?
The Leviton AFCI breaker carries a 10 kiloamp short circuit current rating, which covers the available fault current on typical residential and light commercial branch panels. If the utility transformer feeding the building puts more than 10kA of available fault current at the panel, this breaker is not the right device and you need a higher AIC breaker. Get the available fault current calculation for the service before you commit on a commercial job.
3) What is the difference between an AFCI breaker and a regular thermal magnetic breaker?
A standard thermal magnetic breaker only trips on overload and short circuit. The Leviton LB115-AF is an AFCI, an arc-fault circuit interrupter, so on top of overcurrent protection it watches the waveform for the signature of an arcing fault, the kind you get from a nicked conductor or a loose termination, and opens the circuit. That is the protection the NEC requires on dwelling unit bedroom and living area circuits. A thermal magnetic breaker like the Square D PowerPacT B or the ABB E150 Series gives you overcurrent protection only and will not satisfy an arc-fault requirement.
4) Can I put a Leviton AFCI breaker in a Square D or Eaton panel?
No. The Leviton LB115-AF is built for Leviton load centers. Plug-on breakers are only listed for the panelboards their manufacturer specifies, and dropping a breaker of one brand into another brand's bus is not a listed installation even when it physically seats. If your panel is a Square D, you need a Square D breaker for that load center. If you are building the panel new, match the breaker line to the load center line.
5) Will this AFCI breaker work on a 240V circuit or a two-wire multiwire circuit?
No. This is a 1-pole device rated 15A at 120V, so it protects a single 120V branch circuit only. A 240V load, or a shared-neutral multiwire branch circuit, needs a 2-pole breaker so both ungrounded conductors open together.
6) Can a Square D Multi9 C60 miniature breaker be used in place of a Leviton LB115-AF for an arc-fault circuit?
No. The Leviton LB115-AF is an AFCI device, meaning it monitors the branch circuit for hazardous arcing and interrupts power when it detects it, in addition to normal overcurrent protection. The Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC; it handles overcurrent only and does not provide arc-fault detection. If the circuit is one where arc-fault protection is called for, the AFCI breaker is the device that satisfies it. The C60 is the choice where plain overcurrent protection on a 120V branch is all that is required.
7) I need arc-fault protection but I only see molded case breakers like the Square D PowerPacT B. Will that work?
The Square D PowerPacT B is a thermal magnetic molded case breaker, a feeder and main class device that trips on overload and short circuit. It is not an arc-fault device. For a 15A or 20A 120V single-pole branch circuit that needs arc-fault detection, the Leviton AFCI breaker in 1-pole 15A or 20A is the correct device. A molded case thermal magnetic breaker can sit upstream of it, but it does not replace the AFCI function downstream.
8) Is the ABB ST200M a substitute for a Leviton AFCI breaker in a panelboard?
They are listed to different standards and serve different roles. The ABB ST200M is a miniature circuit breaker built to UL1077, which is a supplementary protector standard, used to protect components inside equipment rather than to serve as branch circuit protection in a panel. The Leviton AFCI is a branch circuit breaker with arc-fault detection and a 10 kiloamp short circuit rating, intended for load center and panelboard branch circuits. For a protected branch circuit in a panel, the AFCI breaker is the device that fits that role.
9) I am upgrading an older panel to meet arc-fault requirements. Is this the right breaker to swap in?
For panel upgrades and retrofits, this is the intended use, provided the load center is Leviton. Swapping a standard 15A single-pole breaker for the LB115-AF adds arc-fault detection to that branch circuit without rewiring. Two things to sort out first: the AFCI needs the circuit neutral landed on the breaker rather than the neutral bar, and the circuit must not share a neutral with another circuit or the AFCI will nuisance trip.
10) What should I use instead if I need arc-fault protection on a three-phase commercial feeder?
Not this one. The Leviton AFCI is a single-pole 120V branch device, built for individual branch circuits and not for feeders or three-phase distribution. For three-phase molded case protection, look at the ABB A2N Series 3-pole molded case breaker or the Square D PowerPacT Q I-Line, both 3-pole distribution devices. Those provide overcurrent protection, not arc-fault detection.
11) Is this a plug-on breaker or does it mount on DIN rail?
The Leviton LB115-AF is a load center branch breaker, not a DIN rail device. If your application is a DIN rail enclosure or control panel, the Square D Multi9 C60 and the C60 UL489 miniature breaker are DIN rail mount instead, and the ABB ST200M is a UL1077 supplementary protector. None of those are arc-fault devices.
12) What is the difference between the Leviton LB120-AF and a Square D C60 UL489 DIN rail breaker?
Two different mounting worlds and two different protection types. The Leviton LB120-AF is a 20A AFCI branch breaker built for load centers and panelboards, with arc-fault detection and a 10 kiloamp short circuit rating. The Square D C60 is a UL489 miniature circuit breaker that mounts on DIN rail, which is the format used in control panels and industrial enclosures rather than a residential load center. Choose the Leviton where you are filling a panelboard slot on a dwelling or commercial branch circuit; choose the DIN rail MCB where the enclosure is rail-mounted.
13) What should I use instead of the Leviton AFCI breaker for a 3-pole feeder?
The Leviton AFCI is a 1-pole device and will not serve a three-phase feeder. For 3-pole applications, the ABB A2N Series A2 molded case breaker, the ABB E150 Series thermal magnetic breaker, and the ABB XT4 Series molded case breaker kit are all 3-pole devices. None of them provides arc-fault detection, so if a downstream branch circuit still requires AFCI, that protection is added at the branch breaker level.
14) For an I-Line panel, is the Leviton AFCI breaker the right branch device?
No. I-Line panelboards take breakers built for that bus system, such as the Square D PowerPacT Q I-Line circuit breaker. The Leviton AFCI is a 1-pole 15A or 20A 120V branch breaker for standard load center and panelboard applications and is not an I-Line device. Confirm the panel bus and interior style before ordering either one.
15) Can these Leviton AFCI breakers be installed in an unconditioned space like an attic or a garage panel?
The Leviton AFCI breaker is rated to an operating temperature of 85 degrees Celsius, so heat in a garage, attic, or mechanical room panel is not an issue for the device itself. Note that ambient temperature above the panel's own rating can still require derating of the circuit conductors.
16) How much does a Leviton single-pole AFCI breaker weigh for a shipping estimate?
Each Leviton AFCI breaker weighs 0.42 pounds. Country of origin is Mexico, which is worth noting if you are filing on a project with domestic sourcing requirements.
