Leviton Series 2000 Medium MMU, 480VAC 3P/4W

The Leviton is a Series 2000 Medium MMU (Modular Metering Unit) engineered for 480VAC 3P/4W electrical service, providing dependable, code-compliant metering infrastructure for commercial and industrial buildings. This unit is configured for specific amperage ratings to match the load requirements of the installation and can be ordered with an optional demand feature for facilities that need load-demand monitoring alongside standard consumption metering. It ships with CTs Not Included, giving installers and engineers the flexibility to specify current transformers sized correctly for the application rather than being locked into a fixed CT package. The Medium MMU platform is available in 2-Meter, 3-Meter, or 4-Meter configurations, making it a practical fit for multi-tenant, multi-circuit, and mixed-use metering projects that require several meter positions within a single modular enclosure.

Key Features

  • Electrical Rating: Rated for 480VAC, 3-Phase/4-Wire (3P/4W) service, suited to demanding commercial and industrial power distribution systems.
  • Series 2000 Platform: Built on Leviton's Series 2000 metering line, designed for dependable, long-term field performance.
  • Medium MMU Configuration: Sized as a Medium Modular Metering Unit (MMU), fitting mid-scale multi-metering installations where space and meter count both matter.
  • Configurable Amperage Ratings: Configured for specific amperage ratings so the unit can be matched precisely to project load calculations.
  • Optional Demand Feature: Available with an optional demand feature for facilities that require load-demand tracking in addition to standard energy metering.
  • CTs Not Included: Ships without current transformers, allowing CTs to be selected and sized independently for the specific application and amperage rating.
  • Flexible Meter Count: Offered in 2-Meter, 3-Meter, or 4-Meter configurations to accommodate multi-occupancy and multi-circuit metering needs within one unit.

Leviton 2M402-CFG – Frequently Asked Questions

1) Does the Leviton Series 2000 Medium MMU come with current transformers?
No. The Series 2000 Medium MMU ships with CTs not included, so you specify and order current transformers separately, sized to the amperage rating of each metered circuit. Plan the CT selection as part of the order or the unit will land on site without the sensors it needs to meter.
2) Will a Leviton Series 2000 Medium MMU work on 208V service?
No. This Medium MMU is built for 480VAC 3-phase, 4-wire service. If your electrical room is 208Y/120 or another voltage, you need the Series 2000 unit configured for that service instead, not this one.
3) How many meter positions can I get in one Leviton Series 2000 Medium MMU?
Two, three, or four. The 2-meter unit is MPN 2M402-CFG, the 3-meter is 2M403-CFG, and the 4-meter is 2M404-CFG. Pick the count by how many tenants or circuits you are billing at that location; for more positions you would gang additional units or step up in the Series 2000 line.
4) Can this Leviton Medium MMU be mounted outdoors or in a wet location?
No. The enclosure is NEMA 1, indoor rated only. It belongs in a dry electrical room or interior utility space. An outdoor meter bank, a parking structure, or any location exposed to weather or washdown needs a rainproof enclosure instead.
5) What do I have to specify when ordering a Series 2000 Medium MMU?
Three things beyond meter count: the amperage rating the unit is configured for, whether you want the optional demand feature, and the current transformers, which are ordered separately. The CFG suffix on the part numbers reflects that these are configured-to-order units, so the load calculation needs to be settled before the order goes in.
6) Can I read this Leviton MMU remotely for tenant billing?
The metering provides pulse output, so each meter position can feed a pulse-counting input on a building automation system, a data logger, or a third-party submetering or billing head end. It is not a native network protocol interface, so plan the billing system around pulse collection hardware.
7) Do I need the demand feature on a submeter, or is standard energy metering enough?
If you are only billing kWh consumption to tenants, the standard configuration covers it. The optional demand feature is what you add when the facility is on a utility rate with demand charges, or when the owner wants to allocate peak demand back to individual tenants. It has to be specified at order time, so decide before the unit is built.
8) Is the Leviton Series 2000 Medium MMU suitable for apartment submetering?
Yes, where the service is 480VAC 3P/4W. Typical uses are multi-tenant commercial metering, apartment and mixed-use buildings, industrial distribution, and owner-billed submetering, in both new electrical rooms and metering retrofits. The 2, 3, and 4 meter configurations are what make it fit a small tenant count in one enclosure.
9) Where is Leviton Series 2000 metering equipment made?
The Series 2000 Medium MMU is manufactured in the USA, which matters on public and institutional jobs carrying domestic sourcing requirements in the spec.
