Circuit Breaker TUYA HS081997 2‑Pole 80A Wi‑Fi RS485

Circuit Breaker TUYA HS081997 is a 2‑pole, 80A DIN‑rail mounted smart switch designed for protecting and remotely controlling two separate electrical circuits. It provides Wi‑Fi (2.4 GHz) connectivity and an RS485 interface for local integration, and includes two external Wi‑Fi antennas. The unit monitors electrical parameters such as energy consumption, voltage, current and power factor, and supports overload, short-circuit, leakage and overvoltage protection.

Advantages

The TUYA HS081997 combines protective switching with smart energy metering, allowing real-time monitoring and automatic control based on configurable thresholds. Remote control is available via the TuyaSmart or SmartLife mobile apps (Android, iOS) and voice assistants Amazon Alexa and Google Assistant. The device supports RS485 integration, DIN‑rail installation, and includes visual Wi‑Fi signal indication, a network detection button, mechanical lock and an opening/closing handle for convenient installation and maintenance.

Suitable for

• Residential distribution boards for controlling and protecting two circuits
• Light commercial installations requiring remote monitoring and control
• Applications needing energy consumption metering and threshold-based automatic shutdown
• Smart home setups integrated via Tuya platform or RS485 networks

How to use

Mount the TUYA HS081997 on a standard 35×7.5 mm DIN rail in the distribution board and connect the two circuits according to wiring standards. Attach the supplied Wi‑Fi antennas and power the device from the specified AC supply (100–230 V). Install the TuyaSmart or SmartLife app on a smartphone or tablet, follow the app pairing procedure to add the device to your Wi‑Fi network, and configure RS485 settings if local integration is required. Use the app or voice assistants to monitor consumption, set unit energy price, and program schedules or thresholds for automatic shutdown.

Usage recommendations

For reliable wireless operation ensure a stable 2.4 GHz Wi‑Fi signal at the mounting location and secure antenna orientation. Configure threshold values (power/current/voltage) carefully according to the protected equipment ratings to prevent unintended shutdowns. Use RS485 integration for local telemetric systems where continuous monitoring or centralized control is required.
