Socket Plus (type G) Jeweller

Smart plug with protection against sparks and electric arc

Socket Plus (type G) Jeweller



Jeweller communication technology

Proprietary wireless technology for transmission of events.

It features:
  • Two-way communication.
  • Advanced anti-sabotage.
  • Block encryption featuring a dynamic key.
  • Instant notifications.
  • Remote configuration via the Ajax apps.

Frequency bands

866.0 – 866.5 MHz
868.0 – 868.6 MHz
868.7 – 869.2 MHz
905.0 – 926.5 MHz
915.85 – 926.5 MHz
921.0 – 922.0 MHz

Depends on the sales region.

Maximum effective radiated power (ERP)

up to 20 mW

Automatic power control to reduce power consumption and radio interference.

Radio signal modulation


Radio communication range

up to 3,600 ft

Between plug and hub or range extender in an open space.

Radio signal encryption

All the data stored and transmitted are protected by block encryption with a dynamic key.

Radio frequency hopping

Radio communication uses frequency hopping to prevent interception and jamming.

Actuating element

Electromagnetic relay

Closes and opens the electric circuit. Designed for more than 200,000 switches.

Energy consumption parameter check

Energy consumption monitoring

  • voltage
  • load current
  • power consumption
  • energy consumed
Values available in Ajax apps. The frequency of parameters update depends on the Jeweller (or Jeweller/Fibra) polling interval. The initial value is 36 seconds.

Maximum current protection

1–16 A

For regular loads, we recommend using current values up to 13 A. Values between 13 and 16 A can only be used for short-term loads.
The value is set in the device Settings in Ajax apps.

Load current

up to 13 A (up to 5 seconds)

Current protection (constant load)

3 A — fluorescent lamps

8 A — incandescent lamps

13 A — general inductive loads

Additional features

Spark and arc protection

triggers if an arc occurs in a device or conductor connected to the socket

If arc protection is activated, power is not restored automatically. Power supply can be restored with a command in the Ajax app or by pressing the function button.

Operation modes



Adjustable pulse duration

1 to 255 s

Set up in Ajax apps. The setting is available when the socket operates in pulse mode.

LED indication

Informs about the state of the socket, as well as the level of power consumed by the connected devices. The exact power consumption value is available in the socket States in Ajax app.

Temperature protection

203 °F

The socket turns off automatically if the temperature is exceeded.

Contact state

normally open (NO)

normally closed (NC)

Set up in the socket settings. Can be set for both pulse and bistable operation modes.


  • by alarm
  • reaction to security mode change
  • scheduled actions
  • by pressing Button
  • by temperature
  • by humidity
  • by CO2 concentration
  • by pressing LightSwitch


The device is designed only for indoor installation. Has a British standard (type G) socket and plug.

Anti-sabotage protection

Protection against forgery

device authentication

Communication loss detection

from 36 s

Detection time depends on the Jeweller (or Jeweller/Fibra) settings.

Power supply

Power supply voltage

230 V~ ± 10%

50 Hz

Output power

up to 3 kW

If protection is installed for a current of 13 A at a 230 V~ resistive load. For 380 V~ inductive or capacitive load, the maximum value of the switched current goes down to 8 A.

Average power consumption of the device

≤ 1.5 W

Overvoltage protection

minimum — 184 V~

maximum — 253 V~

This protects connected appliances from voltage surges. Hub administrator or PRO with system configuration rights can disable this protection.

Electric shock protection class

class I

With grounding terminal.



2.1″ × 2.1″ × 2.2″
