Description
Ajax 42855.13. BL3 WallSwitch (9NA) UPC black
Product Details
WallSwitch Jeweller is a wireless power relay that switches a 110/230 V~ supply on command, handling loads up to 3 kW. Unlike the LightSwitch parts it is not a wall plate — it is a compact module that goes behind an existing switch, in a back box or on a DIN rail, and takes over whatever it is wired to.
It reports energy consumption back to the Ajax app, so a circuit's usage is visible rather than guessed at. Automation scenarios can drive it from arming and disarming, a schedule, an alarm, or temperature, humidity and CO₂ readings — which is what turns it into site lighting on a timetable, presence simulation while a property is empty, underfloor heating, irrigation, or power to a gate or camera.
Built-in protection cuts the load on overcurrent above 11 A, on voltage outside 184–253 V~ (or 92–132 V~ on a 110 V supply), and on internal temperature above 149 °F. It runs in bistable or pulse mode with an adjustable pulse of 1 to 255 seconds, and Jeweller radio reaches up to 3,250 ft.
