3P + 3P Dual Power Manual Transfer Switch (MTS) – Lets you manually switch between two three-phase AC power sources (e.g., grid and generator/backup), ensuring continuous supply when one source fails.
Integrated Circuit Breaker (MCB) Protection – Combines transfer switch functionality with overload, short-circuit, under-voltage, and phase-loss protection in one unit for safer operation.
Three-Phase Compatibility (3P + 3P) – Designed for balanced switching of all three phases between two input sources, suitable for industrial, commercial, and large-load three-phase systems.
Wide Voltage & Frequency Support – Compatible with 230 V / 400 V AC and works on both 50 Hz and 60 Hz networks.
Manual Operation – User-controlled changeover without automation, giving direct control over which source is supplying power.
Wide Current Range – Available in various current ratings (e.g., 6 A up to 63 A), allowing selection based on load requirements.
High Breaking Capacity (~6 kA) – Built to safely interrupt fault currents and protect the circuit during overloads and short-circuit events.
DIN-Rail Mountable Design – Easy installation in electrical panels and distribution boards with standard DIN-rail mounting.
Adjustable Over‑Voltage Protection — Cuts power when phase voltage exceeds the set safe level to protect equipment from high‑voltage damage.
Adjustable Under‑Voltage Protection — Disconnects supply if phase voltage drops below the set threshold to avoid brown‑out damage.
Over‑Current Protection — Protects circuits from over‑current conditions with adjustable current limits.
Three‑Phase Balance & Asymmetry Protection — Detects phase imbalance (asymmetry) and trips to prevent damage to motors and other loads.
Phase Sequence Protection — Ensures correct phase order and prevents reversal faults that can damage three‑phase equipment.
Adjustable Timing Controls — Active time, reconnect delay, and power‑on delay are adjustable to fine‑tune protection response.
Manual Voltage & Current Calibration — Allows precise calibration of measurement ranges to match specific system requirements.
DIN‑Rail Mountable Design — Standard 35 mm DIN‑rail installation for easy panel mounting.
Wide Use Cases — Suitable for industrial, commercial, and residential three‑phase systems to protect motors, compressors, HVAC units, and other loads.
2-Pole AC Surge Protection Device – Protects single-phase electrical systems from voltage surges and transient over-voltages.
High Surge Current Capacity (20 kA ~ 40 kA) – Can absorb and divert high-energy spikes from lightning strikes or switching surges to safeguard devices.
Rated Voltage ~275 V AC (up to 385 V versions) – Designed for typical household and light commercial AC mains.
Low Let-Through Voltage (< 1.5 kV) – Limits the voltage that reaches connected equipment during a surge, reducing damage risk.
Compact DIN-Rail Mountable – Easy installation in electrical panels or distribution boards.
Flame-Retardant Durable Build – Made with robust materials for long-term reliability.
Auto-Reset After Surge – Resets itself after handling a surge event for continuous protection.
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.
