Leviton AFCI Hydraulic Magnetic Branch Circuit Breaker

The Leviton AFCI Hydraulic Magnetic Branch Circuit Breaker delivers dependable arc-fault and overcurrent protection for branch circuits in panelboards and load centers. Built around a hydraulic magnetic trip mechanism rather than a purely thermal design, it provides consistent, temperature-stable tripping performance regardless of ambient conditions, while AFCI (Arc-Fault Circuit Interrupter) protection helps guard against dangerous arcing faults. This breaker is available in multiple pole, amperage, and voltage configurations — including 2-pole, 20A, 120/240V AC arrangements — to suit a range of branch circuit protection needs in commercial, industrial, and residential electrical distribution systems.

Key Features

  • AFCI Protection: Arc-Fault Circuit Interrupter technology helps detect and interrupt dangerous arcing conditions on the branch circuit.
  • Hydraulic Magnetic Trip Mechanism: Provides stable, temperature-independent tripping response for reliable overcurrent protection compared to purely thermal designs.
  • Branch Circuit Protection: Designed specifically to safeguard individual branch circuits within a panelboard or load center from overload and short-circuit conditions.
  • Pole Configuration Options: Available in various pole arrangements, including 2-pole configurations, to suit single-phase and multi-phase branch circuit applications.
  • Amperage and Voltage Ratings: Offered in ratings such as 20A at 120/240V AC to match branch circuit load and system voltage requirements.
  • Leviton Engineering: Manufactured by Leviton, a recognized supplier of electrical distribution components for commercial, industrial, and residential applications.
  • Panelboard Compatibility: Sized and configured for installation in compatible panelboards and load centers as part of a coordinated branch circuit protection scheme.
  • Consistent Performance: Hydraulic magnetic construction reduces nuisance tripping associated with ambient temperature swings, supporting long-term circuit reliability.

Leviton LB215-AF – Frequently Asked Questions

1) What amperage options does the Leviton LB-AF series AFCI breaker come in?
Two amperage ratings are sold: 15A as part number LB215-AF and 20A as LB220-AF. Pick the one that matches the conductor size and load on the branch circuit you are protecting. Both are the same AFCI hydraulic magnetic breaker otherwise.
2) Is the Leviton AFCI hydraulic magnetic breaker a 2-pole 120/240V device?
Yes. It is built as a 2-pole breaker rated 120/240V AC, so it lands on two bus poles and serves single-phase 120/240V branch circuits. A single-pole 120V-only circuit is not what this device is configured for.
3) Do I need an AFCI breaker or will a standard miniature circuit breaker do?
AFCI adds arc-fault detection on top of overload and short-circuit protection, catching arcing in damaged or loose branch wiring that a plain breaker ignores. The Leviton LB-AF breakers carry that AFCI function. If the circuit does not call for arc-fault protection and you only need overcurrent, standard miniature breakers such as the Square D Multi9 C60 1-pole or the ABB ST200M cover that, but neither is listed as an AFCI device.
4) Can I use the Leviton AFCI breaker in a commercial panelboard, or is it residential only?
It is meant for branch circuit protection in panelboards and load centers across commercial, industrial, and residential distribution. It has to physically fit and be listed for the panel you are installing it in, so match it to a compatible Leviton load center rather than dropping it into any brand of panel.
5) What should I use instead of the Leviton AFCI breaker for a 3-phase feeder rather than a 120/240V branch circuit?
The Leviton AFCI hydraulic magnetic breaker is a 2-pole device rated 120/240V for branch circuit protection. For three-phase distribution, the ABB A2N Series molded case breaker and the ABB E150 Series thermal magnetic breaker are both 3-pole devices, and the ABB XT4 Series is supplied as a 3-pole molded case breaker kit. Those are overcurrent devices without the arc-fault function.
6) Is there an alternative to the Leviton LB215-AF or LB220-AF breaker if the panel needs a DIN rail mounted device instead of a panelboard branch breaker?
The Leviton AFCI hydraulic magnetic breaker is built as a branch circuit breaker for installation in compatible panelboards and load centers, in 15A and 20A versions ordered as LB215-AF and LB220-AF. For a DIN rail assembly, the Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, and the Square D Multi9 C60 1-pole C-curve miniature breaker is rated 120V AC. Those are overcurrent-only miniature breakers, so they do not provide the arc-fault detection the Leviton unit carries.
7) Can a UL1077 supplementary protector be used in place of the Leviton LB220-AF branch breaker?
No. The Leviton LB220-AF is a 20A AFCI branch circuit breaker intended to protect individual branch circuits in a panelboard or load center. The ABB ST200M miniature circuit breaker is built to UL1077, which covers supplementary protection rather than branch circuit protection, so it is not a drop-in equivalent. If a UL489 miniature breaker is what the drawing calls for, the Square D C60 UL489 MCB is the closer match, though it does not include arc-fault detection.
8) What is the difference between a hydraulic magnetic breaker and a thermal magnetic one for branch circuits?
A hydraulic magnetic trip, like the one in this Leviton AFCI breaker, responds the same way regardless of ambient temperature, so a hot mechanical room or a cold outbuilding does not shift the trip curve or cause nuisance trips. A thermal magnetic breaker uses a bimetal element whose response drifts with ambient heat. If you want the thermal magnetic style instead, the ABB E150 Series 3-pole thermal magnetic breaker and the Square D PowerPacT B thermal magnetic breaker are the comparable choices.
9) Does the Leviton LB-AF breaker mount on DIN rail?
It is a plug-in branch breaker for panelboards and load centers, not a DIN rail component. If your assembly is DIN rail based, the Square D C60 UL489 miniature circuit breaker is the DIN rail mount option.
10) Which Leviton part number do I order for a 20 amp AFCI two-pole circuit?
Order LB220-AF. That is the 20A version; LB215-AF is the 15A. Both are 2-pole, 120/240V AFCI breakers.
11) How does the Leviton hydraulic magnetic AFCI breaker differ from a thermal magnetic breaker like the Square D PowerPacT B?
The Leviton breaker uses a hydraulic magnetic trip mechanism, which the manufacturer describes as giving temperature-stable tripping regardless of ambient conditions, and it adds arc-fault detection on the branch circuit. The Square D PowerPacT B is a thermal magnetic circuit breaker, where the overload element responds thermally, and the ABB E150 Series is likewise a thermal magnetic design. Both of those are overcurrent protection only.
12) For an I-line panelboard, is the Leviton AFCI breaker the right choice?
The Leviton AFCI hydraulic magnetic breaker is a 2-pole 120/240V branch breaker for compatible panelboards and load centers, and it is not an I-line style device. Where the panel is I-line, the Square D PowerPacT Q I-line circuit breaker is the I-line format option, and the Square D PowerPacT B is a thermal magnetic molded case breaker. Neither provides arc-fault detection, so an AFCI requirement would have to be met elsewhere on the circuit.
