Leviton Series 3500 Multi-Function Power Meter, 208-480VAC 3-Phase 3W/4W, 1600A

The Leviton Series 3500 Multi-Function Power Meter is engineered to deliver accurate, real-time energy monitoring for commercial and industrial electrical systems. This IndoorSeries 3500 meter communicates over both Modbus TCP and BACnet IP, allowing it to integrate directly with building automation systems, energy management platforms, and network-based monitoring software. Designed with a universal voltage input of 208-480VAC, the meter is configured for 3-Phase 3-Wire/4-Wire service and is rated for up to 1600A, making it well suited for main service entrances, switchboards, and large panelboards. The Series 3500 is available in multiple configurations - 16M, 1M, 2M, 30M, 4M, 50M, and 8M - so electrical contractors and facility managers can select the monitoring point count needed for a given installation.

Key Features

Leviton 3NUMT-16M – Frequently Asked Questions

1) What does the 16M, 8M, 2M suffix mean on the Leviton 3NUMT power meter?
The number is the monitoring point count. The Series 3500 comes as 3NUMT-1M, -2M, -4M, -8M, -16M, -30M and -50M, so you pick based on how many metering points the installation needs. One panel main with no branch submetering points at 1M; a panelboard where you're tracking 30 or 50 individual circuits takes the 30M or 50M. All of them share the same 208-480VAC 3-phase input and 1600A rating, so the suffix is purely about how many points you're capturing.
2) Will the Leviton Series 3500 meter work on a 480V 3-wire delta service?
Yes. The Series 3500 is configurable for 3-phase 3-wire or 3-phase 4-wire, and the voltage input is universal 208 to 480VAC, so it covers a 480V 3-wire delta as well as a 208Y/120 or 480Y/277 four-wire wye. You set the service type at configuration rather than ordering a different model.
3) Can I use this Leviton power meter on a 1600A main service entrance?
That is what it is rated for. The Series 3500 handles up to 1600A, which puts main service entrances, switchboards and large panelboards inside its range. Current transformers sized to the service are what actually connect it to the conductors, so the CTs need to match the amperage at the point you are metering.
4) Does the Leviton 3500 meter talk to BACnet, or is it Modbus only?
Both, over Ethernet. The Series 3500 supports Modbus TCP and BACnet IP, so it drops onto a building network and reports to a BAS front end or an energy management platform without a protocol gateway. If your controls contractor is standardized on BACnet IP and your energy platform polls Modbus TCP, the same meter serves both.
5) Can the Leviton Series 3500 power meter be mounted outdoors or in a wet location?
No. It carries an Indoor (NEMA 1) enclosure, which is general-purpose indoor only, no protection against rain, splashing or hose-down. For an exterior service entrance or a washdown area you need the meter inside a suitably rated enclosure or a separate NEMA 3R/4X box.
6) Is the Leviton 3500 suitable for tenant submetering in a multi-tenant building?
Yes, submetering and load monitoring are among its intended uses. The higher point-count versions are the ones that matter here: a 30M or 50M lets you capture many tenant circuits off one panelboard from a single meter rather than installing individual meters per tenant. Data is pulled back over Modbus TCP or BACnet IP for billing or tracking.
7) Do I need to order current transformers separately with the Leviton 3500 meter?
Plan on it. The meter itself is the measurement and communication device rated to 1600A on a 208-480VAC 3-phase service; the CTs that clamp the conductors are sized to the actual load at each point you are monitoring, and a 50-point version needs far more of them than a 1-point. Confirm CT quantity and amperage against your one-line before you place the order so the meter and the sensors arrive together.
