Original price £110.00
Current price £88.00

The RA2 Select family of in-line dimmers and switches can control lighting and motor loads both locally and remotely when paired with Pico wireless controls or Radio Powr Savr occupancy / vacancy sensors.

This provides a system that is convenient and easy to install. RA2 Select in-line load controls use Lutron patented Clear Connect RF technology which provides reliable, wireless communication with other RA2 Select devices.

Each load control can be controlled individually using a Pico wireless control.

Using a RA2 Select main repeater allows devices to be part of a whole house solution that can be controlled remotely from anywhere in the world.


  • The dimmer is trailing edge capable of 1 W minimum load and up to 250 W of LED, incandescent, halogen, or ELV loads.
  • The switch is rated for 6 AX of general purpose lighting load and 2 A 0.5 HP of motor load.
  • Allows remote control from anywhere in the space when paired with Pico wireless controls.
  • When used with the RA2 Select main repeater, the load controls can be programmed via the Lutron App* to incorporate lighting scenes and schedule daily events. Also, the load controls can also be controlled from anywhere in the world.
  • To maximize energy savings and provide hands-free operation, load controls can be turned on/off automatically via Radio Powr Savr occupancy /vacancy sensors. • Small size allows for simple retrofit installation.
  • Remote device association allows for in-line controls to be added to a system without physically accessing product.



220–240 V~ 50/60 Hz

Typical Power Consumption

Dimmer/Switch: < 0.5 W Test conditions: Load and LED are off

Regulatory Approvals 



Ambient operating temperature: 0 °C to 40 °C (32 °F to 104 °F), 0% to 90% humidity, non-condensing. Indoor use only


RA2 Select in-line load controls communicate with the system through Radio Frequency (RF). They must be located within 18 m (60 ft) line-of-sight or 9 m (30 ft) through walls of a Pico wireless control, Radio Powr Savr sensor, or RA2 Select repeater. System devices operate at 868 MHz

ESD Protection

Tested to withstand electrostatic discharge without damage or memory loss, in accordance with IEC 61000-4-2.

Surge Protection

Tested to withstand surge voltages without damage or loss of operation, in accordance with IEEE C62.41-1991 Recommended Practice for Surge Voltages in Low-Voltage AC Power Circuits.

Power Failure

Power failure memory: should power be interrupted, the control will return to its previously set level prior to the interruption when power is restored.


Allow adequate space to ensure convective cooling of load control. Remove any insulation, heat generating equipment, or obstructions within 120 mm (4.75 in) of the load control.

For optimal RF performance, no metal or other electrically conductive material should be present within 120 mm (4.7 in) around the top and sides of the load control. The load control is not suitable for installation in places where it is fully enclosed in metal (e.g., metal enclosures, electrical cabinets) or within metal ceilings.


RA2 Select in-line controls accept wire gauges between 0.5 mm2 to 2.5 mm2 (20 AWG to 14 AWG).

Note: All outside wire diameters must be the same and must be between 5.2 mm–8.5 mm (0.2 in–0.3 in).

Device Limits

Up to 100 devices (e.g., load controls, Pico wireless controls, Radio Powr Savr sensors, shades, and repeaters) are supported per system.

The main repeater counts as one device and four locations are reserved for wireless repeaters. Note: Load controls have load type and capacity limits. For more information, see Load Type and Capacity
