WDYK MCB 20A 1P is a single-pole, single-phase, high-performance DIN-rail mounted smart circuit breaker with a rated capacity of 20A.

This is the single-pole product version, which only breaks the phase wire. This type does not include a consumption meter function.

The WDYK device is connected to the same eWeLink smart home platform via the Wi-Fi router as the Sonoff or SmartWise devices, so the devices of these brands can be well combined with each other. The smart circuit breaker connects directly to the Wi-Fi router, it does not need a local central unit or hub.

You can set a push message notification in the eWeLink app for switching on and off, so you can request a message on your phone when the circuit breaker is released. With the help of the built-in small motorized switch, it can be turned on and off remotely from the app as well as via the Internet, not just manually on the device.

The maintenance mode lock button on the circuit breaker can be used to disable both smart functions and manual switch-on, so both local switch-on and remote or timed switch-on can be prevented during maintenance of the electricity network.

Using the eWeLink App running on an iOS (Apple) or Android mobile phone with an Internet connection, you can remotely control the device and even set a timed switch on/off. Of course, the device also has a physical switch, similar to what is found on traditional circuit breakers. Remote access can be shared with other users.

The WDYK brand - like Sonoff and SmartWise devices - uses the eWeLink app, so it can be well combined with Sonoff's smart electrical devices.
