Leviton Telcom OSSMD-MAT Dual Relay Mount Wallbox

Product Description

The Leviton Telcom OSSMD-MAT is a dual relay mount wallbox designed for use with compatible occupancy sensor and lighting control systems operating at 120 to 277 volts AC. This mounting hardware accessory provides a structured enclosure solution for housing dual relay modules in wallbox installations. It is typically installed by licensed electricians during new construction or retrofit lighting control projects where relay-based switching is required at the wallbox level.

This unit is suited for commercial and residential lighting control applications where dual relay functionality needs to be housed in a standard wallbox form factor. It supports installations using low-voltage occupancy sensor systems that require relay mounting at the point of control, making it a practical hardware component in structured wiring and energy management setups.
