Circuit breaker TUYA HS084059 1P+N 63A — smart Wi‑Fi-enabled single-pole with neutral

Circuit breaker TUYA HS084059 is a DIN-rail mountable smart switch for electrical circuits, combining overload and short-circuit protection with remote control and energy metering. This 1P+N device rated up to 63A connects via 2.4 GHz Wi‑Fi (TuyaSmart / SmartLife) and includes an RS485 interface, two external Wi‑Fi antennas and a compact housing suitable for residential and light commercial installations.

Advantages

The TUYA HS084059 integrates protection functions (overload, short circuit, overvoltage, leakage and high temperature) with remote on/off control, voice assistant compatibility (Amazon Alexa and Google Assistant) and built-in energy monitoring. It supports app-based real-time readings for voltage, power, temperature and accumulated energy, plus configurable thresholds, timers, scenes and automations. Additional features include mechanical safety lock, Wi‑Fi signal LED, manual ON/OFF lever and RS485 communication for integration with other systems.

Suitable for

• Remote switching and protection of household electrical circuits (lighting, water heaters, ovens)
• Energy monitoring and consumption reporting for billing or accounting
• Integration into smart home automations and scheduled control
• Small commercial or light industrial electrical circuits requiring remote control and metering

How to use

Install the TUYA HS084059 on a 35 mm DIN rail following local electrical codes and switch off power during installation. Connect the live and neutral conductors to the appropriate terminals and attach the included Wi‑Fi antennas. Use the TuyaSmart or SmartLife app (Android, iOS) to add the device to your 2.4 GHz Wi‑Fi network and configure RS485 if required. After registration, you can control the circuit manually via the lever or remotely through the app, create schedules, scenes and set energy thresholds. Verify all connections and test protections after installation.

Usage recommendations

Use the device within its rated voltage and current limits (AC 230 V, max. 63 A). For safety, perform wiring and commissioning by a qualified electrician, enable mechanical lock during maintenance, and periodically check firmware updates and Wi‑Fi signal strength to ensure reliable remote control and accurate energy metering.
