GRD9S-F100WL 2~4P Smart RCBO with WiFi Control

GRD9S-F100WL: The Complete Smart Energy Guard

The GRD9S-F100WL (2P/3P/4P) redefines electrical safety by merging industrial-grade circuit protection with smart home convenience. As the upgraded version of the F100, this Smart RCBO adds critical Residual Current Leakage Protection to the standard overload and short-circuit defenses. Whether for residential homes or commercial power distribution, it offers complete peace of mind through the Tuya Smart / Smart Life App.

Professional Leakage Protection & Safety

Unlike standard MCBs, the F100WL is designed to protect human life and prevent electrical fires.

• ✔ Adjustable Leakage Thresholds: Customize protection from 30mA to 500mA via the App to suit different environments (Default: 50mA).
• ✔ Leakage Self-Test: Schedule automatic self-checks (Day/Hour/Minute) to ensure the RCD mechanism is always functional.
• ✔ Sudden Leakage Protection: Instantly trips if a sudden leakage spike (30-100mA) is detected, preventing immediate shock hazards.

Global Control & Class 1.0 Metering

Eliminate the need for complex RS485 wiring. The device connects directly to your WiFi network.

• Remote ON/OFF: Control circuits from anywhere in the world.
• High-Precision Monitoring: View real-time Voltage, Current, and Power. Track kWh usage with Class 1.0 accuracy to save on energy bills.
• Pre-Payment Function: Set power limits to automatically trip when consumption exceeds your budget.

22+ Integrated Protection Functions

The GRD9S-F100WL is a fully configurable protection shield. Most parameters can be set to “Alarm Only,” “Trip,” or “Disabled” via the App.

• • Over/Under Voltage Protection
• • Over/Under Power Protection
• • Phase Loss & Phase Reversal (3P/4P)
• • Voltage/Current Unbalance
