Smart breakers sit on the DIN rail in your electrical panel and let you switch a circuit on and off from a phone app. This range covers Tuya and Sonoff eWeLink breakers in 1, 2 and 4 pole versions, several with an energy meter or earth leakage protection, plus a Tuya Wi-Fi DIN rail energy meter with an LCD.

Tip: match the pole count and amp rating to the circuit you are replacing, and have a qualified electrician fit it.
