Ajax WallSwitch Jeweller Wireless Mains Power Relay, 13 A with Energy Monitor

Overview

The Ajax WallSwitch Jeweller is a small relay that fits inside a wall box or switchboard to switch mains-powered lights or appliances from the Ajax app or by automation. Because it is wired in behind the switch plate, nothing changes on the wall, and it also reports how much energy the circuit uses. It suits lights, water heaters, gates and other 110 to 230 V loads in homes, shops and offices on an Ajax system.

Is it right for you?

• It suits a wired-in load such as a lighting circuit, a boiler or a gate motor that you want to control through Ajax scenarios.
• Choose it when a plug-in device will not do and the load is up to 3 kW at 230 V (13 A).
• It is indoor only (IP20, 0 to 64 °C) and must be installed by a qualified electrician.
• For low-voltage or dry-contact switching, the Relay Jeweller is the right device instead.

Key features

• Switches 110 to 230 V AC (±10%, 50/60 Hz) loads up to 3 kW resistive at 230 V or 1.5 kW at 110 V, with a maximum continuous current of 13 A.
• Scenarios: on arming or disarming, by schedule, by alarm, by temperature, by humidity or CO2 level (with LifeQuality on the system), or by pressing a Button or touching a LightSwitch.
• Energy monitor showing current, voltage, power and energy consumed.
• Protection that switches the relay off on overcurrent (above 11 A with overcurrent protection on, 13 A with it off), on mains voltage outside 184 to 253 V at 230 V or 92 to 132 V at 110 V, and on overheating above 65 °C.
• Pulse mode (1 to 255 s) or bistable mode, with normally open or normally closed contact state, on firmware 5.54.1.0 or later made after 5 March 2020.
• Class II electric shock protection and consumption of up to 1 W itself.
• Jeweller two-way radio, up to 1,000 m to the hub or range extender in open space, with communication loss detection after 36 s.
• Compact at 39 × 33 × 18 mm and 30 g, black.

What else you need

An Ajax hub or range extender and the Ajax app, plus a 110 to 230 V AC circuit to switch. Mount it on a DIN rail with the DIN Holder, which is sold separately, where possible. Scenarios by humidity and CO2 need a LifeQuality on the system.

Installation

A professional electrician should install the device. It is wired into the wall box or switchboard with the two supplied wires, indoors, and preferably clipped to a DIN rail with the DIN Holder. The electrician or an Ajax installer then adds it to the hub in the app and sets the operating mode.

Software and licences

Switching, scenarios, energy readings and protection settings are managed in the Ajax app.

Before you buy

• Mains wiring: have a qualified electrician fit it.
• The DIN Holder for rail mounting is sold separately.
• Indoor use only, 0 to 64 °C, up to 75% humidity without condensation.
• Maximum 13 A continuous load.
