GWS9-DW LCD Smart WiFi Circuit Breaker

The GWS9-DW smart WiFi circuit breaker combines Tuya app control, an LCD screen, electrical metering, and configurable circuit protection in a compact 1P+N device. It is designed for 90-240V circuits with an adjustable rated current of 1-40A and lets users monitor connected loads locally or remotely.

Monitoring and Control

Real-time readings: view voltage, current, power, temperature, and operating status on the device or in the app.
Energy records: review energy-consumption data by year, month, day, hour, or selected time period.
Remote operation: control the connected circuit through the Tuya app when the device is online.
Timing and prepayment functions: configure scheduled operation and supported metering-prepayment functions for the required application.

Configurable Protection

The GWS9-DW provides configurable overvoltage, undervoltage, overload, high-temperature, and overpower protection. Depending on the selected function, the device can be set to turn off, issue an alarm, or trip. Protection thresholds and delays should be commissioned within the confirmed product limits and the requirements of the connected circuit.

LCD Display

The integrated LCD screen gives technicians a local view of circuit readings and device status without opening the mobile app. This supports faster checking during commissioning, operation, and maintenance.

Installation and Tuya App Pairing

Safety note: installation and wiring must be completed by qualified electrical personnel with the supply isolated. Follow the terminal markings and the latest product manual.

Install the Tuya Smart app and register or sign in.
After wiring and energizing the unit, confirm that a stable WiFi signal is available at the installation point.
Enable WiFi and Bluetooth on the phone, then press the device’s right button twice to enter network-pairing mode.
In the app, select Add Device, wait for device discovery, and select the detected smart meter.
Enter the WiFi credentials, select Next, and wait for the connection to complete.
Select Finish. After successful pairing, the blue indicator changes from flashing to steady. The supplied sheet identifies steady blue as the closing state and no blue light as the opening state.

Applications and B2B Selection

GWS9-DW is intended for circuit monitoring and load-control applications that require remote switching, real-time electrical data, energy records, timing control, prepayment functions, and configurable protection. Before ordering, confirm that the 90-240V operating range, 1P+N configuration, 1-40A adjustable rated current, and Tuya WiFi communication match the intended circuit.

FAQs

1. What is the GWS9-DW smart WiFi circuit breaker?

GWS9-DW is a 1P+N smart circuit breaker with an LCD screen, Tuya WiFi control, electrical metering, and configurable protection functions. Its listed operating range is 90-240V with a 1-40A adjustable rated current.

2. What can the GWS9-DW monitor?

The device can show voltage, current, power, temperature, and circuit status. Energy-consumption records can also be reviewed by year, month, day, hour, or a selected time period through the supported app functions.

3. Which protection functions are available?

The supplied product information lists overvoltage, undervoltage, overload, high-temperature, and overpower protection. Available actions include turn off, alarm, or trip, depending on the selected function and device configuration.

4. Which parameters should be checked before selection?

Confirm the 90-240V operating range, 1P+N pole configuration, required rated current within the 1-40A adjustable range, Tuya WiFi communication, installation environment, and protection thresholds required by the connected circuit.

5. Does the GWS9-DW provide residual-current or leakage protection?

Residual-current or leakage protection is not listed in the supplied GWS9-DW product sheet. If the application requires this function, confirm the correct product configuration or a separate residual-current protection device with GEYA before selection.

6. What should be noted during installation and pairing?

A qualified electrician should install and wire the device with the supply isolated. After commissioning, use a stable WiFi connection, follow the latest Tuya app interface and product manual, and verify all protection settings before controlling the circuit remotely.
