Leviton Telcom 2N480-8D Current Transformer 277 480V

Product Description

The LEVITON TELCOM 2N480-8D is a Series 2000 current transformer designed for use in 277 volt and 480 volt electrical distribution systems. It provides a 800:0.1 turns ratio, stepping down high primary current to a low-level secondary signal suitable for metering, monitoring, and energy management instrumentation. Electricians and electrical contractors install this device during panel builds, retrofit metering projects, and load monitoring upgrades. The 800:0.1 ratio makes it well suited for applications where accurate current measurement at higher ampacity circuits is required.

This current transformer is intended for commercial and light industrial electrical installations operating at 277 volt single-phase or 480 volt three-phase service voltages. Typical applications include revenue-grade metering, building energy management systems, and subpanel monitoring. It is sold as a single unit and is appropriate for installations where panel-mounted or inline current sensing is part of the design.

Key Features

• 800:0.1 turns ratio for high-accuracy current sensing at elevated ampacity circuits
• Rated for 277 volt and 480 volt electrical systems
• Series 2000 construction for consistent metering-grade performance
• Single-unit packaging suitable for individual circuit monitoring applications
• Compact form factor compatible with standard panel and metering enclosure installations

Compatibility

Designed as an OEM-style replacement or new-installation current transformer for 277 volt and 480 volt commercial and light industrial metering and energy monitoring systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines for instrument transformers and metering equipment. De-energize the circuit and verify absence of voltage before installing or removing the transformer. Ensure secondary terminals are never left open-circuited while the primary conductor is energized, as this can produce hazardous voltage. Verify that the primary conductor gauge and system voltage rating are within the transformer specifications before commissioning.
