SONOFF DR — DIN Rail Mount Tray for Sonoff Smart Switches | Switchboard Installation Adapter

SONOFF DR — DIN Rail Mount Tray

The SONOFF DR is a practical, low-cost mounting accessory that solves one of the most common installation challenges for Sonoff smart home users — fitting Sonoff Wi-Fi relay switches neatly and safely inside a standard electrical distribution box on a DIN rail. Most Sonoff switches are not natively DIN rail mountable, making them difficult to install cleanly inside switchboards without this adapter. The DR tray changes that entirely, letting you place your Sonoff devices exactly where they belong: inside your electrical panel alongside your circuit breakers, in a professional, organized, and safe configuration.

Installation is intentionally tool-free. The SONOFF DR features a blue push-and-click locking mechanism that snaps securely onto any standard DIN rail with a simple push, and releases just as easily with a pull, no screwdrivers, no drilling, and no modifications to your electrical cabinet required. Four included M3 screws fit perfectly into Sonoff’s original screw holes, securing your Sonoff device firmly to the DR tray without needing to drill additional mounting points. The whole process takes minutes and results in a clean, stable, professionally mounted installation inside the switchboard.

The DR tray is made from fire-retardant ABS material with a V0 fire safety classification, ensuring it meets the safety standards expected of components installed inside live electrical panels. Compatibility covers the most widely used Sonoff relay products including the Basic R2 and R3, RF R2 and R3, POW R1 and R2, TH10, TH16, Dual R2, and most other standard-sized Sonoff Wi-Fi smart relay switches. Note that the DIN rail itself is not included in the box — the DR is the mounting tray only.

For Lebanese electricians, smart home installers, and DIY automation enthusiasts integrating Sonoff switches into residential or commercial electrical panels, the SONOFF DR DIN Rail Mount Tray is an inexpensive but essential accessory that brings order, safety, and professionalism to every Sonoff switchboard installation.
