Leviton Medium Mini Meter Unit, 120/208V 3P/4W, NEMA 4X

Leviton Medium Mini Meter Unit, 120/208V 3P/4W, NEMA 4X

The Leviton Medium Mini Meter Unit (MMU) is a 120/208V 3P/4W reference voltage metering enclosure built to monitor multiple electrical circuits in a single, compact housing. Configured with 2 dual element meters and a NEMA 4X rated enclosure, this unit is designed for demanding commercial and multi-tenant metering environments where accurate load monitoring and enclosure durability are both required. Current transformers are not included and must be sourced separately to match project ampacity needs. The MMU is available in 6M302-CFG, 6M303-CFG, and 6M304-CFG configurations to suit varying installation requirements.

Key Features

• Reference Voltage Configuration: 120/208V 3P/4W setup supports three-phase, four-wire commercial electrical distribution systems.
• Dual Element Metering: Equipped with 2 dual element meters for accurate, independent monitoring of multiple circuits within one enclosure.
• NEMA 4X Enclosure Rating: Rated NEMA 4X for use in corrosive, washdown, and outdoor environments requiring enhanced ingress protection.
• Multiple Model Configurations: Available in 6M302-CFG, 6M303-CFG, and 6M304-CFG configurations to match project-specific metering requirements.
• Current Transformers Not Included: Current transformers must be ordered separately and matched to the connected load and ampacity.
• Medium Mini Meter Design: Compact MMU housing is suited for space-constrained installations requiring multiple metering points.
