Description
GRD9S-F100W (1~4P) with Energy Metering & Tuya App Control
The GRD9S-F100W Iot circuit breaker redefines electrical safety by combining industrial-grade circuit protection with consumer-friendly wireless technology. Designed for both single-phase (1P/2P) and three-phase (3P/4P) networks, this device acts as a complete energy management system. It supports Tuya/ESP WiFi, Zigbee, and Bluetooth, allowing users to monitor voltage, current, and leakage status from anywhere in the world via smartphone.
Wireless Connectivity & Remote Control
Eliminate the need for RS485 wiring. The F100W connects directly to your local network. Through the Tuya Smart / Smart Life App, you can:
- Remotely switch circuits ON/OFF.
- Set scheduled timers for automatic operation.
- Receive instant push notifications for faults (Leakage, Overload, etc.).
- Perform OTA (Over-the-Air) firmware upgrades.
22+ Integrated Protection Functions
Safety is paramount. The GRD9S-F100W is not just a switch; it is a high-precision shield for your equipment. It features Class 0.5 voltage/current detection accuracy and includes:
- Leakage Protection: Auto-reclosing or alarm modes.
- Phase Protection (3P/4P): Detects Phase Loss, Phase Reversal, and Unbalance.
- Power Quality: Over/Under Voltage, Over/Under Power, and Overload protection.
- Maintenance Lock: Ensures personnel safety during manual repairs.
High-Precision Energy Metering
Transform your distribution box into a smart energy monitor. The device features Class 1.0 Active Energy Metering. It tracks real-time consumption (kWh), helping you identify energy-draining appliances and optimize usage to reduce electricity bills. Data is stored even during power outages.
