Leviton LB-200 2-Pole Plug-On Mount Branch Circuit Breaker, 200A-270A

The Leviton LB-Series is a lineup of plug-on mount branch circuit breakers built to deliver dependable overcurrent protection in residential and light commercial load centers, available in ratings from 200A to 270A. Each breaker in the family is a 2-pole design sized for branch circuits that demand higher amperage capacity, such as larger appliance circuits, sub-panel feeds, and other double-pole loads found in modern electrical systems. The plug-on mount design lets electricians and maintenance professionals install or replace the breaker quickly and securely by seating it directly onto a compatible Leviton load center bus bar, without the extra hardware or wiring steps required by bolt-on style breakers. This makes the LB-Series a practical choice whenever a fast, code-conscious circuit protection solution is needed for a panel upgrade, service call, or new circuit installation.

Key Features

  • Amperage Rating: Available in 200A and 270A configurations to match branch circuit and sub-panel feed requirements.
  • Pole Configuration: 2-pole design supports double-pole branch circuit applications where both legs of a circuit must be interrupted simultaneously.
  • Plug-On Mount: Simplified plug-on connection allows the breaker to snap directly onto a compatible load center bus bar for a fast, secure installation.
  • Standard Branch Circuit Breaker: Purpose-built as a standard branch circuit breaker for everyday residential and light commercial overcurrent protection needs.
  • Model Family: Includes the LB200 and LB270 configurations within the Leviton breaker lineup, simplifying identification and reordering across amperage ratings.
  • Leviton Manufacturing Standards: Produced to deliver consistent, dependable circuit protection performance that electrical contractors can rely on job after job.

Why Leviton?

Leviton is a widely recognized name in electrical wiring devices and circuit protection equipment, and the LB-Series reflects that reputation with plug-on mount, 2-pole breakers built for dependable, repeatable performance across the 200A-270A range. Choosing a Leviton branch circuit breaker gives electrical contractors and facility maintenance teams a straightforward, code-conscious option for keeping load centers protected and properly configured, whether the job is a single breaker swap or a larger panel refresh.

Leviton LB200 – Frequently Asked Questions

1) Will the Leviton LB-200 breaker snap into my existing load center, or does it need to be bolted in?
The LB-200 series is a plug-on mount breaker. It seats directly onto the bus bar of a compatible Leviton load center, so there is no mounting hardware or bolt-on step. That also means it only goes into panels built for Leviton plug-on breakers. If your panel is a bolt-on design or another manufacturer's bus, this is the wrong breaker for it.
2) Is the Leviton LB200 a single-pole or double-pole breaker, and what circuits is it for?
It is a 2-pole breaker, so it interrupts both hot legs at once. That is what you want for 240V double-pole loads: large appliance circuits, sub-panel feeds, and similar higher-amperage double-pole applications in residential and light commercial load centers. For a 120V single-hot circuit you need a 1-pole breaker instead.
3) I need a 3-pole breaker instead of a 2-pole - what should I look at?
The Leviton LB-200 is built only as a 2-pole device, so it cannot serve a three-phase load. For 3-pole applications, the ABB A2N Series molded case circuit breaker is a UL listed 3-pole unit, and the ABB E150 Series is a 3-pole thermal magnetic breaker. The ABB XT4 Series is also offered as a 3-pole molded case breaker kit. All three are molded case designs rather than plug-on load center breakers, so confirm the enclosure and terminal arrangement before ordering.
4) Can I use a DIN rail miniature circuit breaker in place of the Leviton LB-200?
No. The Leviton LB-200 is a plug-on mount breaker that snaps onto a load center bus bar, while the Square D C60 UL489 miniature circuit breaker is a DIN rail mount device and the Square D Multi9 C60 is a 1-pole C-curve miniature breaker rated 120V AC. DIN rail MCBs require a rail-equipped enclosure and are sized for control and small branch loads, not for the 200A to 270A double-pole feeds the LB-200 covers. The two are not interchangeable in a panel.
5) What is the difference between the Leviton LB-200 breaker and a Square D PowerPacT B thermal magnetic breaker?
The Leviton LB-200 is a 2-pole plug-on mount branch circuit breaker rated 200A to 270A, meaning it seats directly onto a compatible load center bus bar with no mounting hardware. The Square D PowerPacT B is a thermal magnetic molded case circuit breaker, a construction style that is typically terminated and mounted rather than snapped onto a panel bus. If the opening is a residential or light commercial load center with a plug-on bus, the LB-200 is the form factor that fits; a molded case breaker such as the PowerPacT B suits enclosure or switchboard mounting instead.
6) What amp ratings does the Leviton LB-Series 2-pole breaker come in?
Two ratings are offered: 200A (model LB200) and 270A (model LB270), covering the 200A to 270A range. Both are 2-pole. Order by model number to avoid a mix-up on a reorder.
7) Can I use the Leviton LB270 as a main breaker in a panel?
The LB-Series is built as a standard branch circuit breaker for overcurrent protection on branch circuits and sub-panel feeds, not as a main. If you need a main disconnect or a service-entrance device, specify a breaker rated for that duty instead.
8) Which Leviton part number do I order for a 200 amp 2-pole plug-on breaker?
LB200 is the 200A version; LB270 is the 270A. Both are 2-pole plug-on mount units in the same LB family, so the only ordering decision is the amperage that matches the circuit you are protecting.
9) Is the ABB ST200M a substitute for the Leviton LB-200?
They serve different roles. The ABB ST200M is a miniature circuit breaker built to UL1077, which is the standard for supplementary protectors rather than branch circuit protection. The Leviton LB-200 is a standard branch circuit breaker in a 2-pole plug-on configuration for load center use. If the drawing calls for branch circuit overcurrent protection in a panel, a supplementary protector like the ST200M does not fill that role.
10) What would I use instead of the Leviton LB-200 in an I-Line panelboard?
The Leviton LB-200 is a plug-on mount breaker intended for Leviton load center bus bars, so it will not land in an I-Line panelboard. The Square D PowerPacT Q I-Line circuit breaker is the unit built for that connection style. Match the panelboard interior first, then the pole count and amperage, since the mounting interface is what rules a breaker in or out.
