Circuit breaker TUYA HS084066 3-pole Wi‑Fi 63 A

Three-pole TUYA HS084066 circuit breaker with built-in 2.4 GHz Wi‑Fi, RS485 interface and integrated energy metering. Rated for up to 63 A, the device is DIN-rail mountable and designed to protect and remotely control three-phase household and light commercial electrical circuits using the TuyaSmart or SmartLife mobile apps. The unit includes two Wi‑Fi antennas and supports voice control via Amazon Alexa and Google Assistant.

Advantages

The TUYA HS084066 combines overload, short-circuit and leakage protection with remote switching and real-time energy monitoring. Installation on a 35 mm DIN rail is straightforward, and the breaker provides multiple control methods (manual lever, app, RS485). Built-in metering supplies voltage, power, temperature and energy data, while configurable thresholds, timers, scenes and automations allow automated shutdowns and scheduled operation. Mechanical safety lock, Wi‑Fi signal indicator and network detection button increase operational safety and serviceability.

Suitable for

• Residential three-phase electrical panels
• Light commercial and small industrial installations
• Remote switching and monitoring of water heaters, HVAC, pumps and large appliances
