ABB MeterMod III 400A Three-Phase Main Lug Panelboard

The ABB MeterMod III 400A Three-Phase Main Lug Panelboard is a three-phase, four-wire metering and distribution panelboard built for commercial and industrial service entrance applications. Rated for 120/240V AC, 208Y/120V AC, and 240/120V AC systems, this panelboard delivers a 400A ampacity with a 100K AIC short-circuit rating, a top/bottom feed configuration, and a main lug only (MLO) design that feeds downstream distribution equipment without an integral main breaker.

Key Features

  • Amperage Rating: Rated for 400A, supporting heavy commercial and industrial electrical loads.
  • Three-Phase, Four-Wire Configuration: Engineered for three-phase, four-wire power distribution in commercial and industrial facilities.
  • Multi-Voltage Compatibility: Rated for 120/240V AC, 208Y/120V AC, and 240/120V AC systems, giving flexibility across common utility voltage configurations.
  • Short-Circuit Rating: Backed by a 100K AIC rating for demanding fault-current environments.
  • Top/Bottom Feed: Configured for top or bottom feed installation, simplifying conduit routing in the field.
  • Main Lug Only (MLO) Design: Main lug only construction is intended to feed downstream distribution equipment rather than incorporate an integral main breaker.
  • MeterMod III Platform: Part of ABB's MeterMod III metering and distribution equipment line.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Commercial and Industrial Service Entrance Equipment
  • Three-Phase Power Distribution Systems
  • Utility Metering Installations
  • Panelboard and Load Center Wiring
  • New Construction and Electrical Retrofit Projects

Why ABB?

ABB is a recognized name in electrical distribution and metering equipment, and the MeterMod III series is engineered for dependable, code-compliant performance in demanding three-phase applications. With a 400A rating, 100K AIC short-circuit capability, and a main lug only design, this panelboard supports reliable power distribution across commercial and industrial service entrance installations. Its top/bottom feed configuration and multi-voltage compatibility (120/240V AC, 208Y/120V AC, and 240/120V AC) allow it to fit a range of common electrical service configurations, making it a practical choice for electricians and contractors specifying three-phase distribution equipment for new construction or retrofit projects.

ABB TMP3L4R – Frequently Asked Questions

1) Does the ABB MeterMod III TMP3L4R panelboard come with a main breaker?
No. The TMP3L4R is main lug only, so there is no integral main breaker in the enclosure. Feed conductors land directly on the main lugs and the panel distributes downstream. If your design requires overcurrent protection at this point, it has to come from an upstream device, or you need a main breaker panel instead.
2) Is 100K AIC enough for a service entrance close to a large utility transformer?
The MeterMod III 400A panelboard carries a 100,000 A interrupting rating, which is the top end of what is normally specified for distribution equipment on a 400A commercial or industrial service. Compare it to the available fault current from your utility's short-circuit letter; if that number is at or under 100kA at this point in the system, the panel is rated for it.
3) Can I bring conduit into this ABB panelboard from the bottom, or does it have to feed from the top?
Either. The TMP3L4R is a top/bottom feed panelboard, so you can route service conduit in from above or below depending on how the meter and riser are laid out. That flexibility matters on retrofits where the existing raceway direction is fixed.
4) What is the ABB MeterMod III used for, and how is it different from an ordinary load center?
MeterMod III is ABB's metering and distribution equipment line, built for service entrance duty rather than branch-circuit panels inside a tenant space. The 400A three-phase version handles utility metering and feeds downstream distribution gear. A standard load center is a branch distribution panel sitting behind a service disconnect; this one is the service equipment itself, which is why it is rated 100K AIC.
5) Is the ABB TMP3L4R suitable for a single-phase 120/240V service?
The TMP3L4R is built as a three-phase, four-wire panelboard. It is rated for 120/240V AC among its voltages, but the configuration is three-phase, so on a straight single-phase residential or small commercial service you would be buying more panel than the service can use. For a single-phase service entrance, specify a single-phase MeterMod unit instead.
6) What exact ABB part number do I order for the 400A three-phase MLO MeterMod III?
The part number is ABB TMP3L4R. That is the 400A, three-phase, four-wire, main lug only MeterMod III unit rated 120/240V AC, 208Y/120V AC and 240/120V AC. Quote that number on the submittal so the approving engineer sees the MLO configuration and the 100K AIC rating.
