Taxnele 80A 3-Phase WiFi Smart Energy Meter & Circuit Breaker | Tuya Smart Life DIN Rail Voltage, Current & Surge Protection Relay (KWS-306WF).

Take absolute control of your three-phase electrical installation with the Taxnele KWS-306WF 80A Three-Phase WiFi Smart Energy Meter and Protection Relay. Designed for commercial distribution boards, residential panels, rental properties, and industrial equipment, this all-in-one unit functions as a precision sub-meter, programmable timer relay, surge protector, and remote circuit controller.

Using the Smart Life / Tuya Smart app, you can monitor live electrical parameters, automate scheduled on/off cycles, and receive instant alerts. If an electrical anomaly occurs—such as a voltage surge, phase imbalance, or current spike—the built-in relay instantly disconnects the circuit to protect connected machinery and appliances, automatically restoring power once operating conditions normalize.

• Comprehensive 8-in-1 Monitoring: Real-time digital color display tracks Voltage (AC 85–290V), Current (0–80A), Active Power (0–23kW), Energy Usage (kWh), Temperature (-20°C to 150°C), Frequency (50/60Hz), Power Factor, and Running Time.

• Smart WiFi & Remote App Control: Connects seamlessly via Tuya Smart / Smart Life app. Control power remotely, set automated schedules, track historical energy consumption, and monitor loads from anywhere.

• Full Multi-Protection & Auto-Reconnect: Safeguards equipment with customizable thresholds for Over-Voltage, Under-Voltage, Over-Current, Over-Power, Over-Temperature, and Voltage/Current Imbalance with automatic reconnection once normal levels restore.

• High-Reliability Magnetic Latching Relay: Zero-power static magnetic holding relay minimizes internal energy consumption while maximizing switching lifespan and operational safety.

• Snap-On DIN Rail Installation: Standard 35mm DIN rail mount with secure buckle mechanism allows fast, screwless integration into distribution boxes, commercial panels, or factory setups.

• Non-Volatile Memory: Power-failure memory ensures all accumulated kWh consumption records, timer settings, and custom threshold limits remain intact during outages.

Technical Specifications

Frequently Asked Questions (FAQs)

Q: Does this unit work on both Tuya and Smart Life applications?

A: Yes, the KWS-306WF is fully compatible with both the Tuya Smart and Smart Life apps on iOS and Android.

Q: What happens when voltage or current exceeds the set threshold?

A: The internal magnetic latching relay triggers an instant shut-off to isolate connected loads. Once voltage and current return to your designated safe ranges, the auto-reconnect feature automatically restores power after the set delay time.

Q: What should I adjust if using this on a 110V AC supply?

A: The default factory settings are calibrated for 220V/230V systems. When operating on 110V AC, adjust the under-voltage protection limit in the app/panel settings prior to full load deployment to prevent false tripping.

Q: Will it lose my accumulated kWh data during a blackout?

A: No. It features built-in power-off memory that retains all cumulative kWh readings, historical stats, and custom limit configurations during outages.
