10-in-1 Smart Protection & Monitoring – Monitors voltage, current, leakage current, total kWh (energy) and protects your circuit.
WiFi Connectivity & App Control – Connects to your home Wi-Fi (2.4 GHz) and lets you remote ON/OFF control, monitor and adjust settings from the Smart Life / TUYA app on iOS/Android.
Adjustable Protection Settings – Set thresholds for over-voltage, under-voltage, over-current, and leakage current via the app or manually.
Voltage & Current Monitoring – Real-time display and tracking of line voltage and current in the app.
Leakage Current Protection – Detects leakage and cuts power to enhance electrical safety.
Energy Consumption Tracking – Shows total kWh usage so you can monitor and manage power consumption.
Scheduled Control & Timer – Create schedules to automate ON/OFF times for your circuits via the app.
Automatic Reconnection with Delay – After a fault trip, it can reconnect automatically with an adjustable delay (1 s to 500 s).
Calibration Feature – Allows calibration for voltage, current, and kW readings for better accuracy.
Voice Assistant Compatible – Works with Google Assistant / Alexa for hands-free control (where supported).
DIN-Rail Mountable – Standard design for installation in electrical panels.
3‑Phase Dual Power Manual Transfer Switch (MTS) – Designed for three‑phase AC systems to manually switch between two independent power sources (e.g., grid and backup/generator), ensuring continuous power supply.
4P + 4P Pole Configuration – Each power source has a 4‑pole module (phases L1, L2, L3 + neutral), providing full control and protection across all conductors.
Integrated MCB Protection – Combines manual transfer switch functionality with a Miniature Circuit Breaker (MCB) to offer overload, short‑circuit, under‑voltage, and phase‑loss protection in one unit.
Manual Operation – User‑controlled changeover between main and backup power sources for reliable fail‑safe switching without automation.
Wide Voltage & Frequency Support – Suitable for 230 V / 400 V AC systems at 50 Hz / 60 Hz frequencies, compatible with a broad range of electrical networks.
Multiple Current Ratings – Available in common ratings such as 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A to match different load requirements.
High Breaking Capacity – Typically around 6 kA, ensuring safe interruption of fault currents during protection events.
DIN‑Rail Mountable – Easy installation in electrical distribution boards and control panels using standard 35 mm DIN rail.
Adjustable Over-Voltage Protection – Cuts off power if voltage rises above your set safe level (e.g., 230–300 V range).
Adjustable Under-Voltage Protection – Disconnects supply when voltage falls below the safe limit (e.g., 140–210 V range).
Adjustable Over-Current Protection – Protects against excessive current with adjustable current range up to 63 A.
Real-Time Monitoring – Built-in voltage meter, ammeter, and energy (kWh) meter for live electrical data.
Delay & Reconnect Settings – Adjustable delay times before protection kicks in and automatic power reconnection after normal conditions return.
Memory of Fault Values – Saves recorded values for over-voltage, under-voltage, and over-current events even after power is off.
LED Indicators – Flashing LEDs show voltage or current protection status when triggered.
DIN-Rail Mountable – Fits easily into electrical panels using a standard DIN rail.
Dual Power Manual Transfer Switch (MTS) – Allows you to manually switch between two AC power sources (e.g., main grid and backup generator).
1P + 1P Configuration – Uses two single-pole modules—one for each power source—ideal for single-phase systems.
Built-in Circuit Breaker (MCB) – Provides overload and short-circuit protection during power source switching.
Safety Interlocking System – Prevents both power sources from being connected at the same time to avoid back-feeding and electrical hazards.
Manual Operation – Simple, user-controlled switching between power supplies without automated control.
Wide Frequency Support: Works with 50 Hz / 60 Hz AC systems.
