Wi-Fi Smart Reclosing Protector

This is an "all-in-one" intelligent protector, typically managed via a mobile app like Tuya Smart or Smart Life.

1. Electrical Protection

The device provides comprehensive safety by actively monitoring the circuit:

• Over-Voltage Protection (>U): It automatically cuts power if the voltage rises above a safe, pre-set threshold.

• Under-Voltage Protection (<U): It cuts power if the voltage drops below a safe, pre-set threshold (protecting sensitive electronics from 'brownouts').

• Over-Current/Overload Protection (>A): It trips if the current exceeds its rated limit for a sustained period, similar to an MCB.

• Automatic Reclosing (The "Reclosing" part): If the device trips due to a temporary fault (like a brief power surge or voltage dip), it will automatically wait and then attempt to reconnect the circuit. If the fault persists, it will lock out to prevent damage.

2. Smart (Wi-Fi) Functions

The Wi-Fi connectivity makes this device a smart energy management tool:

• Remote Control: You can switch the power ON or OFF from anywhere using the connected smartphone app.

• Energy Monitoring (V, A, L, Pulse): The display and app allow you to monitor critical electrical parameters in real-time:

  • V: Voltage (e.g., $220V$)

  • A: Current (Amperes)

  • L: Wattage/Power (often shown in the app as kW or kWh, which is the $\text{V} \times \text{A}$ calculation)

  • Pulse/kWh: Energy consumption metering (Kilowatt-hours)

• Time Scheduling: Set up schedules and timers to automatically turn the circuit on or off.

• Voice Control: Compatible with voice assistants like Amazon Alexa and Google Assistant for hands-free control.

 Installation and Use

• Form Factor: It is designed for DIN rail mounting inside an electrical distribution box or panel.

• Primary Application: It is typically installed as the main incoming protector or as a sub-main circuit protector to safeguard an entire section of a residential or commercial electrical installation.
