Eaton BR Series Main Lug Load Center

The Eaton BR Series Main Lug Load Center is engineered for reliable power distribution in commercial, industrial, and general electrical service applications. This main lug load center platform is available in two configurations to match project requirements: a 125A single-phase model housed in a NEMA 1 enclosure with 16 circuits for indoor distribution, and a 150A three-phase, four-wire model housed in a NEMA 3R enclosure with 42 circuits across 24 spaces for outdoor and wet-location service. Built to Eaton's widely specified BR Series design, this main lug load center delivers the circuit capacity, enclosure protection, and phase configuration needed for panelboard replacement, service upgrades, and new construction projects requiring dependable distribution equipment.

Key Features

  • Amperage Range: Available in 125A and 150A main lug configurations to match branch circuit and feeder distribution needs.
  • Circuit Capacity: 16 circuits in the 125A single-phase configuration, or 42 circuits across 24 spaces in the 150A three-phase configuration, providing room for growing load requirements.
  • Phase Configuration: Offered in single-phase (125A) and three-phase, four-wire (150A) versions for compatibility with a range of commercial and industrial distribution systems.
  • Enclosure Options: NEMA 1 enclosure for indoor installations in the 125A configuration, and NEMA 3R enclosure for outdoor and wet-location installations in the 150A configuration.

Eaton BR816L125SP – Frequently Asked Questions

1) What is the difference between the two Eaton BR main lug load centers, 3BR2442LC150R and BR816L125SP?
Two very different panels. The BR816L125SP is 125A single-phase in a NEMA 1 enclosure with 16 circuits, meant for indoor distribution. The 3BR2442LC150R is 150A three-phase four-wire in a NEMA 3R enclosure, 42 circuits across 24 spaces, rated for outdoor and wet-location service. Pick by phase first, then enclosure: a single-phase service cannot use the three-phase panel.
2) Can an Eaton BR main lug load center be mounted outdoors?
Only the 150A three-phase version, model 3BR2442LC150R, which is built in a NEMA 3R enclosure suitable for outdoor and wet-location installation. The 125A single-phase BR816L125SP is NEMA 1, indoor dry locations only. Putting the NEMA 1 panel outside, even under an overhang, is not what it is rated for.
3) Does a main lug load center need a separate upstream breaker?
Yes. Main lug means there is no integral main breaker in the panel, so the feeder has to be protected by overcurrent device ahead of it. The Eaton BR main lug load center is built for feeder-fed branch circuit distribution, so plan on upstream protection sized to the panel, 125A or 150A depending on which version you order.
4) What voltage is the Eaton BR series main lug load center rated for?
120/208/240V. That covers 120/240V single-phase for the 125A NEMA 1 panel and 120/208V three-phase four-wire for the 150A NEMA 3R panel. If your service is 277/480V, this is not the panel for it.
5) Is the bus in the Eaton BR load center copper or aluminum?
Aluminum bus. If your spec or inspector calls for a copper bus panelboard, this will not meet it. Aluminum bus is standard on the BR line and is what most residential and light commercial specs accept.
6) How many breakers will fit in the 150A three-phase BR panel?
The 3BR2442LC150R has 24 spaces and accepts up to 42 circuits, so full-size breakers fill the 24 spaces and tandem-capable positions get you to the 42-circuit count. Useful headroom on a panel replacement where the load is expected to grow.
7) I'm replacing a 16-circuit indoor subpanel in an apartment building. Which BR load center matches?
The BR816L125SP, 125A single-phase in a NEMA 1 enclosure with 16 circuits, is the indoor subpanel configuration. Being main lug, it lands on a feeder from the main service with the overcurrent protection upstream, which is how most apartment subpanels are fed.
