Leviton LB130-T 30A-120V Thermal-Magnetic Circuit Breaker

The Leviton LB130-T is a 30A, 120V thermal-magnetic circuit breaker engineered to deliver dependable overcurrent protection in residential and light commercial panelboards. Combining a thermal element for sustained overload protection with a magnetic trip mechanism for rapid response to short-circuit conditions, this breaker is built to interrupt fault current quickly and help protect branch-circuit wiring and connected equipment. Its 30A-120V rating makes it a common choice for standard single-pole branch circuits requiring reliable, code-compliant circuit protection, and it is designed as a straightforward replacement or addition when upgrading or servicing a compatible panelboard.

Key Features

  • Amperage Rating: 30A trip rating sized for standard branch-circuit loads.
  • Voltage Rating: 120V rating suited to common residential and light commercial circuits.
  • Thermal-Magnetic Trip: Dual protection design combines a thermal element for sustained overloads with a magnetic element for fast-acting short-circuit response.
  • Panelboard Compatibility: Designed to install into compatible Leviton load centers and panelboards as a direct branch-circuit protection device.
  • Overcurrent Protection: Helps safeguard branch-circuit conductors and connected devices from damage caused by excess current draw.
  • Reliable Switching: Provides manual on/off circuit control in addition to automatic trip protection, simplifying circuit isolation during maintenance.
  • Model Identification: Model LB130-T is clearly marked for easy identification when specifying replacement or additional breakers for an existing panel.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Residential Panelboard and Load Center Circuits
  • Light Commercial Branch-Circuit Protection
  • Circuit Breaker Replacement and Panel Upgrades
  • New Construction Electrical Distribution
  • Renovation and Service Panel Maintenance
  • Single-Circuit Isolation for Electrical Servicing

Why Leviton?

Leviton is a long-established name in electrical distribution products, and the LB130-T thermal-magnetic breaker reflects that focus on dependable, code-compliant circuit protection. By pairing a thermal overload element with a magnetic short-circuit trip in a single 30A-120V device, Leviton gives electricians and facility managers a straightforward way to protect branch circuits without sacrificing reliability. For professionals specifying panelboard components, choosing a Leviton breaker means selecting a device built for consistent performance in demanding electrical distribution environments, whether the job is a new installation, a panel upgrade, or a targeted circuit replacement.

Leviton LB130-T – Frequently Asked Questions

1) What amperage and voltage is the Leviton LB130-T circuit breaker rated for?
The LB130-T is a 30A, 120V single-pole branch-circuit breaker. That rating suits standard 30A single-pole branch circuits in residential and light commercial panelboards. If your circuit draws more than 30A or runs at a different voltage, this is not the right device.
2) Will the Leviton LB130-T breaker fit in my existing panel?
The LB130-T is built to install into compatible Leviton load centers and panelboards as a branch-circuit protection device. Breakers are panel-specific, so if your load center is another manufacturer's, this one is not a drop-in. Check the panel label for the accepted breaker family before ordering.
3) I need a single-pole breaker on a DIN rail instead of a load center - what should I use instead of the Leviton LB130-T?
The Leviton LB130-T is built to install into compatible Leviton load centers and panelboards, not onto DIN rail. For DIN rail work, the Square D 60109 Multi9 C60 is a 1-pole C-curve miniature circuit breaker, and the Square D C60 UL489 miniature circuit breaker is specified as DIN rail mount. The ABB ST200M Series miniature breaker is a C-curve device listed to UL1077. Note that UL1077 devices are supplementary protectors rather than branch-circuit breakers, so for branch-circuit protection the UL489 C60 is the one to look at.
4) What is the closest thermal-magnetic alternative to the Leviton LB130-T for a panel that does not take Leviton breakers?
The Leviton LB130-T is a 30A, 120V thermal-magnetic breaker designed to install into compatible Leviton load centers and panelboards, so it is not a drop-in for another manufacturer's panel. If the panel is a Square D molded-case enclosure, the Square D PowerPacT B thermal magnetic circuit breaker uses the same dual thermal-plus-magnetic trip approach in a molded case body. On the ABB side, the E150 Series 3-pole thermal magnetic circuit breaker is also a thermal-magnetic design. Both are a different mounting family from the LB130-T, so confirm the panel interior accepts the chosen series before ordering.
5) Can I use the Leviton LB130-T on a three-phase feeder?
No. The LB130-T is a 30A, 120V device intended for standard single-pole branch circuits. For three-pole applications you need a different family: the ABB A2A150TT is an A2N Series 3-pole molded case breaker, the ABB E150 Series is a 3-pole thermal magnetic breaker, and the ABB XT4 Series is offered as a 3-pole molded case breaker kit. The Square D PowerPacT Q is an I-Line breaker for I-Line panel bussing.
6) What does thermal-magnetic mean on a 30A breaker, and do I need it?
Two trip mechanisms in one device. The thermal element responds to sustained overloads, heating up and tripping when a circuit is pulled beyond 30A for a period of time. The magnetic element reacts fast to short-circuit faults, interrupting the current quickly. For general branch-circuit wiring protection in a panelboard, that pairing is what you want. It is not a ground-fault or arc-fault device.
7) What part number do I order to replace a breaker in a Leviton panel?
Order by the model marking: LB130-T. Leviton marks the model on the breaker body, so pull the existing device and read it. The LB130-T covers the 30A, 120V single-pole position.
8) For a larger molded-case application than the Leviton LB130-T covers, what are the options?
The LB130-T is a 30A, 120V single-pole branch-circuit device. When the application calls for a molded case frame instead, the Square D PowerPacT B is a thermal magnetic molded case breaker, the ABB A2A150TT is an A2 Series molded case breaker, and the ABB XT4 Series is supplied as a molded case breaker kit. The Square D PowerPacT Q is an I-Line style breaker for I-Line distribution panels. All four are feeder-class and mount into their own equipment families rather than a residential load center.
9) Is a C-curve miniature breaker the same thing as the Leviton LB130-T?
They are not interchangeable. The LB130-T is a 30A, 120V thermal-magnetic breaker that drops into a compatible Leviton panelboard for branch-circuit protection. The Square D 60109 Multi9 C60 and the ABB ST200M are C-curve miniature circuit breakers, a curve-classified miniature format sized to equipment and motor inrush rather than to a residential load center interior. They look similar in size but mount and specify differently, so a C-curve MCB is a design choice for the panel, not a swap into a Leviton load center.
10) Can I use the LB130-T to isolate a circuit while I work on it?
Yes. Beyond automatic trip protection, the breaker gives manual on/off control of the circuit, so an electrician or maintenance tech can kill a single branch circuit at the panel during servicing without dropping the whole load center.
11) Is the LB130-T suitable for a commercial building panel?
It is sized for residential and light commercial branch circuits. Typical uses are load center circuits, panel upgrades, new construction distribution, and one-for-one breaker replacement during service work. For heavier commercial distribution gear you would be looking at molded case equipment instead, such as the Square D PowerPacT line or the ABB XT4 Series.
