Leviton Telcom LU20S-DNW Wireless Relay 20A 120-277V

Product Description

The LEVITON TELCOM LU20S-DNW is a wireless relay designed for switching and load control in commercial and residential lighting or power circuits. Rated at 20 amps and compatible with supply voltages from 120 to 277 volts, it supports a wide range of single-phase AC applications. The relay receives wireless control signals to open or close a circuit without requiring a dedicated low-voltage control wire run to the switch location. Licensed electricians install this device as part of wireless lighting control, occupancy-based switching, or building automation systems.

The LU20S-DNW is suited for commercial lighting control installations where running traditional switch legs is impractical or cost-prohibitive. Typical applications include retrofit projects in offices, warehouses, and commercial tenant spaces where a wireless switching solution reduces conduit and wiring labor. It handles standard 20-amp branch circuit loads including fluorescent, LED, and general-purpose receptacle circuits operating at 120, 208, 240, or 277 volts.

Key Features

• 20-amp relay rating supports standard commercial branch circuit loads
• Wide voltage range of 120 to 277 volts covers common single-phase AC supply configurations
• Wireless operation eliminates the need for dedicated low-voltage control wiring
• Sold as an individual unit for flexible single-point installation

Compatibility

Designed as an OEM-style wireless relay for use within compatible wireless lighting control and load management systems. Consult system documentation to confirm protocol and controller compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the branch circuit at the panel and verify absence of voltage with a meter before making any wiring connections. Do not exceed the 20-amp load rating of the relay. Follow the manufacturer wiring diagram for line, load, and neutral connections, and ensure the wireless receiver is within the operational range of the system controller before finalizing the installation.
