-
Intelligent Remote Control: This is the core smart feature. It allows you to remotely turn the circuit ON or OFF using a mobile phone app (likely a common platform like Tuya Smart or Smart Life).
-
Time Setting Function: This enables you to set automatic schedules (timers) for the power to be switched on or off, making it useful for lights, heaters, or water pumps.
-
Overload Protection (Adjustable 1A-63A): This is a key safety feature. It acts as an adjustable circuit breaker, tripping and cutting power if the current exceeds a value you can set (anywhere from 1 Amp up to 63 Amps).
-
Over/Under Voltage Protection (145V-300V): The device protects connected appliances by automatically disconnecting the power if the voltage goes too high ($>300V$) or too low ($<145V$).
-
Large Capacity: The advertised Max Power of 15000W (or $15\text{kW}$) at 230V is consistent with the 63A maximum current rating ($230V \times 63A \approx 14,490W$).
Comparison to the Previous Device
| Feature | Previous Device (Smart Reclosing Protector) | This Device (Intelligent Remote Switch) |
| Primary Function | Protection (Over/Under V, Over C, Reclosing) | Remote Control & Timer (with protection) |
| Current Rating | Implied $\leq 63\text{A}$ | Adjustable 1A - 63A |
| Key Difference | Automatic Reclosing capability to restore power after a temporary fault. | Emphasizes Remote ON/OFF and Timing control. |
| Form Factor | Both are DIN rail mounted and use a similar digital display for V/A/Power. | Both are used to control and protect an entire electrical circuit or sub-circuit. |
In short, this device is a highly capable smart switch that provides customizable voltage and current protection, remote control, and energy monitoring for high-power single-phase loads
