Leviton OutdoorSeries 3500 Multi-Function Power Meter Kit, 1600A Split Core CTs

The Leviton OutdoorSeries 3500 Multi-Function Power Meter Kit delivers accurate, code-compliant energy monitoring for commercial and industrial 3-phase electrical systems installed in outdoor environments. Built for universal voltage applications spanning 208-480VAC, this meter kit communicates via both Modbus TCP and BACnet IP protocols for seamless integration into building management, submetering, and energy monitoring systems. The kit supports 3 Phase 3W/4W (3-wire/4-wire) service configurations and ships complete with 1600A Split Core current transformers (CTs), simplifying installation on existing outdoor electrical services without the need to disconnect live conductors. This meter kit is designed for facility managers, electrical contractors, and energy service providers who need dependable, protocol-flexible metering data from a single outdoor-rated device.

Key Features

  • Universal Voltage: 208-480VAC universal voltage input supports a wide range of commercial and industrial electrical services, reducing the need for multiple meter SKUs across different service voltages.
  • Multi-Protocol Communication: Modbus TCP and BACnet IP connectivity provide flexible integration with building automation systems, energy management platforms, and third-party monitoring software.
  • 3-Phase Metering: Configured for 3 Phase 3W/4W (3-wire/4-wire) circuits, delivering accurate multi-function energy data across common commercial and industrial service types.
  • Split Core CTs Included: 1600A Split Core current transformers are included in the kit, allowing installation around existing conductors without disconnecting or de-energizing the circuit.
  • OutdoorSeries Design: Purpose-built OutdoorSeries 3500 meter housing is designed for outdoor electrical service applications where the metering point is located outside the building envelope.
  • Multi-Function Metering: As a multi-function meter, the OutdoorSeries 3500 is designed to capture the broader set of power and energy parameters typically required for submetering and energy management applications.
  • Multiple Configuration Options: Available in multiple configuration options (16M, 1M, 1SM, 2M, 2SM, 30M, 4M, 4SM, 50M, 8M) to match specific mounting and installation requirements on site.

Leviton 3OUMT-1SM – Frequently Asked Questions

1) Can the Leviton 3500 meter be mounted outdoors at the service without a separate weatherproof enclosure?
Yes. The OutdoorSeries 3500 meter kit uses a NEMA 4X outdoor-rated enclosure, so it is built to sit at an outdoor metering point rather than inside the building envelope. That is the whole point of the OutdoorSeries housing, and it is why contractors use it where the service disconnect is on an exterior wall or pad.
2) Will the Leviton OutdoorSeries 3500 meter work on a 480V 3-phase service, or do I need a different voltage model?
One model covers it. The 3500 takes a universal 208-480VAC input, so the same kit serves 208V, 240V, 277/480V and the voltages between, on either 3-phase 3-wire or 4-wire service. For a facility with mixed service voltages across buildings, that means standardizing on one meter rather than stocking a meter per voltage.
3) Do I have to shut down the service to install the CTs on this Leviton meter kit?
No. The kit ships with 1600A split core current transformers, which hinge open and clamp around the existing conductors. You do not have to land the conductors through a solid core window, so an energized retrofit on a live outdoor service is possible without pulling the feeders. Standard electrical safe work practices still apply when opening the gear.
4) Does the Leviton 3500 talk to a BACnet building automation system, or is it Modbus only?
Both. The 3500 supports Modbus TCP and BACnet IP over the same Ethernet connection, so it drops into a BAS front end on BACnet or into an energy management or submetering platform on Modbus without a protocol gateway. That matters on campus and healthcare jobs where the BAS is BACnet but the energy platform wants Modbus registers.
5) What are the configuration options on the Leviton 3OUMT meter kit and how do I order the right one?
There are ten configurations, ordered as a suffix on the 3OUMT base: 1M, 1SM, 2M, 2SM, 4M, 4SM, 8M, 16M, 30M and 50M. So a single-meter unit is 3OUMT-1M, an eight is 3OUMT-8M, and a fifty is 3OUMT-50M. Pick the configuration that matches the number of metering points and the mounting arrangement at the site, because the suffix is the ordering decision, not a field setting.
6) How does the Leviton OutdoorSeries 3500 meter kit compare to the Square D PowerLogic PM5560 for an outdoor service metering point?
The Leviton OutdoorSeries 3500 kit is supplied in an outdoor NEMA 4X enclosure and ships with 1600A split core CTs, so it is intended to be mounted at the service outside the building envelope without adding a separate weatherproof housing or sourcing CTs separately. The Square D PowerLogic PM5560 is a PowerLogic series power meter with Ethernet and 63rd harmonic analysis, which is where the two diverge: the PM5560 is chosen when deep harmonic analysis is the requirement, while the 3500 kit is chosen when the metering point itself sits outdoors and needs universal 208-480VAC 3-phase 3W/4W metering over Modbus TCP or BACnet IP out of the box.
7) We need power quality and harmonic data, not just energy totals - is the Leviton 3500 kit the right choice?
If harmonic analysis is the driver, look at the Square D PowerLogic PM5560, which is specified with 63rd harmonic analysis. The Leviton OutdoorSeries 3500 is a multi-function meter aimed at the power and energy parameters used for submetering and energy management on 3-phase 3W/4W services, packaged with 1600A split core CTs in an outdoor NEMA 4X enclosure. For a tenant submetering or BAS energy-monitoring program at an outdoor service, the 3500 kit covers it; for power quality investigation work, the PM5560 is the meter built around that.
8) What size service can the 1600A CTs in this Leviton kit actually meter?
The CTs supplied are rated 1600A, so the kit is sized for large commercial and industrial services up to that ampacity, typically a main switchboard or a large tenant feeder. If your feeder is a fraction of 1600A, you lose resolution at the low end, so match the CT rating reasonably close to the actual load for good submetering data.
9) Is this Leviton meter kit suitable for tenant submetering in a multi-tenant building?
Yes, that is one of its intended uses. The multi-function metering captures the broader set of power and energy parameters submetering programs need, and the higher-count configurations such as 3OUMT-8M, 3OUMT-16M and 3OUMT-50M exist so one outdoor enclosure can cover many tenant points. Data comes out over Modbus TCP or BACnet IP to whatever billing or energy platform you run.
10) Can I use this Leviton meter on a 3-wire delta service, or is it 4-wire wye only?
Both work. The 3500 is configured for 3 Phase 3W and 4W circuits, so it handles a 3-wire delta as well as a 4-wire wye with a neutral. Confirm which one you are on before you wire the voltage references, since the connection differs between the two even though the meter itself covers each.
11) Do I still need to buy current transformers if I order the Leviton 3500 meter kit?
No. The Leviton OutdoorSeries 3500 kit ships with 1600A split core CTs, which clamp around existing conductors so the service does not have to be de-energized to install them. That is a packaging difference worth checking against the Square D PowerLogic PM5560, which is catalogued as the power meter itself - CT selection and sizing for that one is a separate line on the order. On the Leviton side you are picking among configuration options such as 1M, 2M, 4M, 8M, 16M, 30M and 50M rather than specifying CTs.
12) My BAS speaks BACnet IP, not Modbus - is the Square D PM5560 a drop-in alternative to the Leviton 3500 kit?
Not on the communications side as described. The Leviton OutdoorSeries 3500 kit lists both Modbus TCP and BACnet IP, so it can be dropped onto a BACnet IP building automation system directly. The Square D PowerLogic PM5560 is described as a power meter with Ethernet and 63rd harmonic analysis; if your integration requirement is native BACnet IP alongside Modbus TCP from one device, the Leviton 3500 kit is the one that states both protocols. Confirm protocol licensing with the BAS integrator before committing either way.
13) Is the Leviton 3500 power meter made in the USA?
Yes, the OutdoorSeries 3500 meter kit is listed with USA country of origin, which is the answer government, education and other publicly funded buyers usually need before a purchase order clears domestic sourcing review.
