Leviton Telcom 2R480-21 3-element Meter 277/480V 3ph

Product Description

The LEVITON TELCOM 2R480-21 is a 3-element revenue-grade electric meter designed for 277/480 volt, 3-phase, 4-wire electrical systems. It measures energy consumption across all three phases simultaneously, making it suitable for monitoring multi-phase loads in commercial and light industrial applications. The 3-element configuration captures full system metering data, giving electrical contractors and facility electricians an accurate picture of load distribution. This meter is sold as an individual unit and is intended for installation by a licensed electrician familiar with 3-phase metering equipment.

This meter is applied in commercial buildings, industrial facilities, and multi-tenant properties where 277/480 volt, 3-phase, 4-wire service is present. Typical installations include submetering applications for tenant billing, energy auditing, and load monitoring on distribution panels fed by a wye-configured transformer. It is suited for environments where accurate 3-phase energy data is required at the panel or circuit level.

Key Features

• 3-element metering captures energy data across all three phases of a 4-wire system
• Rated for 277/480 volt, 3-phase, 4-wire electrical service
• Single-unit packaging for individual installation or retrofit
• Designed for commercial and light industrial submetering applications
• Compatible with standard meter socket enclosures used in 3-phase metering installations

Compatibility

Designed as an OEM-style replacement or new-installation meter for 277/480 volt, 3-phase, 4-wire metering sockets in commercial and light industrial electrical systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Shut off and lock out the upstream service disconnect before handling meter socket connections. Verify that the meter socket form factor matches the 2R480-21 before installation. Do not install in systems with voltage or phase configurations outside the rated 277/480 volt, 3-phase, 4-wire specification.
