Product Description

The ShopwithSIA Smart Safety Series presents the professional's choice for electrical panel upgrades.

Key Features & Benefits:

  • 10-in-1 Complete Protection: Includes Over-Voltage, Under-Voltage, Over-Current, Earth Leakage, Temperature sensing, Short Circuit prevention, and more.  

  • Dual Line Isolation (L+N): For maximum safety, this model cuts both the Live and Neutral wires simultaneously during a fault, ensuring no residual current remains in your circuit.  

  • Precision Energy Metering: Track your electricity usage (kWh) with calibration support (-9.9% to 9.9%). It’s the perfect "Prepaid Meter" for sub-let portions or shops.

  • Adjustable Safety Thresholds: Customize your protection via the app:

    • Under-Voltage: 140V – 210V (Safe start for ACs/Inverters)  

    • Over-Voltage: 225V – 295V (Protects against surges)  

    • Over-Current: 1A – 63A (Prevents wire melting)  

  • Intelligent Auto-Reclosing: If a fault is temporary, the breaker will wait for your preset "Reconnect Time" (1s–500s) and restore power automatically once the grid is safe.  

  • Smart Automation & Scheduling: Use the built-in timer to automate heavy loads like water pumps or outdoor lighting. Compatible with Google Assistant and Alexa for voice control.  

  • Low Power Consumption: Operates at less than 2W, ensuring the device itself doesn't add to your electricity bill.  

  • Global Visibility: Check your leakage current and total load history graphs anytime, anywhere, ensuring you never face unexpected billing surprises.
