Lutron Wireless Dimmer Module RRK-R25NE-240

The Lutron Wireless Dimmer Module RRK-R25NE-240 from the RA2 Select range is a single-zone in-line load control dimmer designed for domestic lighting control. The unit is part of Lutron's RA2 Select platform and communicates wirelessly using Clear Connect RF at 868 MHz, enabling pairing with Pico controls, occupancy/vacancy sensors and a main repeater.

Its capsule-shaped, matte-black housing and slim profile are intended for installation in restricted spaces such as ceiling voids or junction boxes. Integral mounting tabs and a compact footprint allow installation through a typical downlight cut-out, making it suitable for retrofit work.

Constructed from engineered plastics with a clear front label, the module includes a manual push-button, LED status indicator, a QR code for commissioning and a wire-stripping guide marked at 5 mm. The front panel also identifies the device as a single zone controller for straightforward system integration.

Electrically the dimmer is reverse-phase (trailing-edge) capable: up to 250 W for incandescent/halogen/ELV loads and up to 1 A/150 W for LED. The associated switch ratings include 6 AX for general lighting and 2 A/0.5 HP for motor loads. A four-speed fan control is rated for a single AC ceiling fan up to 100 W; it must not be used with DC motor fans, fans with integrated light control modules, fans with remote controls, Wi‑Fi‑only fans, or shaded-pole type motors.

The RRK-R25NE-240 can be programmed via the Lutron App when used with the RA2 Select main repeater and is supplied for wireless commissioning and control within an RA2 Select installation. Its small size and clear labelling simplify retrofit installation, but installers should observe the printed wiring and strip-length guidance during fitting.

At Lighting Design Online we frame this Lutron module as a practical way to achieve considered, reliable control in domestic schemes. Its compact form and Clear Connect RF make it a discreet, project-friendly choice for adding dimming to existing ceilings, while the compatibility with Pico controls and occupancy sensors supports layered, flexible lighting that helps create the right ambience and balance for a room.
