Leviton Plug-On Mount GFCI Branch Circuit Breaker

The Leviton Plug-On Mount GFCI Branch Circuit Breaker combines branch circuit overcurrent protection with built-in ground-fault circuit interrupter (GFCI) safety in a single plug-on device, such as the Leviton LB230-G configured as a 2-Pole, 30-Amp, 120/240-Volt AC breaker. This family is available in 1-Pole and 2-Pole configurations, with amperage ratings of 20A or 30A and voltage ratings of 120V or 120/240V AC, giving installers a flexible GFCI breaker solution for compatible plug-on load centers and panelboards. Device Type: GFCI.

Key Features

  • Pole Configuration: Available in 1-Pole and 2-Pole options to match circuit and panel requirements.
  • Amperage Ratings: Offered in 20A and 30A ratings for a range of branch circuit loads.
  • Voltage Ratings: Available in 120V and 120/240V AC to support single and split-phase circuits.
  • Plug-On Mount: Plug-on design allows direct installation into compatible load centers and panelboards without additional mounting hardware.
  • Integrated GFCI Protection: Device Type is GFCI, providing ground-fault sensing along with standard branch circuit overcurrent protection.
  • AC Rated: Engineered for AC branch circuit applications consistent with the specified voltage and amperage options.

Leviton LB120-GFT – Frequently Asked Questions

1) What amperage, pole, and voltage combinations does the Leviton plug-on GFCI branch circuit breaker come in?
Two configurations. The LB120-GFT is a 1-pole, 20A, 120V breaker, and the LB230-G is a 2-pole, 30A, 120/240V breaker. Pick the 1-pole for standard 120V branch circuits like kitchen, bath, or outdoor receptacle runs, and the 2-pole when you need ground-fault protection on a split-phase 240V circuit.
2) Do I need a separate GFCI receptacle if I install this Leviton breaker?
No. The Leviton plug-on breaker is a GFCI device type, so ground-fault sensing is built into the breaker along with normal branch circuit overcurrent protection. It protects the entire circuit from the panel out, so downstream outlets can be standard devices.
3) Will this Leviton GFCI breaker fit my existing load center?
It is a plug-on mount breaker, so it snaps directly onto the bus of a compatible plug-on load center or panelboard with no separate mounting hardware. That also means it is panel-specific: it only seats in load centers built for Leviton plug-on breakers, not in a bolt-on or DIN rail panel.
4) Which breaker do I use for a 240V circuit, the 1-pole or 2-pole Leviton GFCI?
Use the 2-pole LB230-G. It is rated 30A at 120/240V AC and takes both hot legs of a split-phase circuit. The 1-pole LB120-GFT is 20A at 120V only and cannot serve a 240V load.
5) Is the ABB ST200M miniature circuit breaker an equivalent to the Leviton LB120-GFT?
They serve different roles. The Leviton LB120-GFT is a 1-pole, 20A, 120V plug-on GFCI breaker that stabs onto a load center bus and provides ground-fault protection. The ABB ST200M is a miniature circuit breaker built to UL1077, which is a supplementary protector standard rather than a branch circuit overcurrent device, and it is not a ground-fault product. For branch circuit protection in a panelboard with GFCI required, the Leviton unit is the correct choice.
6) What is the difference between this Leviton GFCI breaker and a molded case breaker like the Square D PowerPacT?
Different jobs. The Leviton is a plug-on branch circuit breaker with GFCI ground-fault sensing built in, sized 20A or 30A for individual circuits. Molded case units such as the Square D PowerPacT B thermal magnetic breaker or the ABB A2N Series 3-pole are feeder and main-level overcurrent devices, and nothing in our record on them indicates ground-fault personnel protection. If the requirement is GFCI protection on a branch circuit, the Leviton is the device type you want.
7) I need three-phase protection, will this Leviton GFCI breaker work?
No. The Leviton plug-on GFCI comes only in 1-pole and 2-pole, 120V or 120/240V AC. For three-phase you would look at a 3-pole molded case unit such as the ABB A2N Series or the ABB E150 Series thermal magnetic breaker.
8) For panel work on a DIN rail assembly rather than a plug-on load center, what 120V option is there besides the Leviton GFCI breaker?
The Leviton plug-on GFCI breaker mounts by plugging directly onto the bus of a compatible load center or panelboard, so it will not land on a DIN rail. For a DIN rail assembly at 120V AC, the Square D Multi9 C60 1-pole C-curve miniature circuit breaker is rated 120V AC, and the Square D C60 UL489 MCB is a DIN rail mount device. Both are overcurrent-only, so keep the Leviton breaker where the circuit calls for ground-fault protection.
9) Would a Square D PowerPacT Q I-Line breaker work for a 30A 120/240V GFCI circuit?
It would not cover the ground-fault requirement. The Leviton LB230-G is a 2-pole, 30A, 120/240V AC plug-on breaker whose device type is GFCI, so it handles both the overcurrent and the ground-fault function on that circuit. The Square D PowerPacT Q is an I-Line breaker, a distribution-style device that mounts to an I-Line panelboard rather than a plug-on load center bus. If the 120/240V circuit needs GFCI at the breaker, the Leviton LB230-G is the device built for it.
10) Is this Leviton breaker suitable for a commercial panel or only residential?
Both. Leviton lists these plug-on GFCI breakers for residential and commercial panelboards, load center circuit protection, panel upgrades and retrofits, and new construction wiring, provided the panel accepts Leviton plug-on breakers.
