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.
Single-Phase Compatibility – Best for homes, small businesses, and backup power setups.

The TOMZN 1P+1P MTS AC Dual Power Manual Transfer Switch is a manual transfer switch combined with MCB protection designed for single-phase AC electrical systems. It lets you safely switch between two power sources (such as the main grid and a backup generator) by hand, making it ideal for homes, small businesses, and backup power setups. The built-in interlocking mechanism ensures only one source is active at a time, preventing electrical hazards, while the integrated circuit breaker offers overload and short-circuit protection during power transitions. Compatible with 50 Hz and 60 Hz systems and easily mounted on a standard DIN rail, this switch helps maintain reliable and safe power management in dual-source applications.

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.
2P + 2P DC Manual Transfer Switch (MTS) – Lets you manually switch between two DC power sources in a photovoltaic (PV) setup, such as a solar array and a backup battery bank.
Dual Power Operation – Designed for DC dual power systems to ensure continuity of power without automatic switching.
Rated for High DC Voltage: Supports up to 1000 V DC, meeting common PV system requirements.
Integrated Circuit Breaker Protection: Combines manual transfer switching with overload and short‑circuit protection in one unit.
2P + 2P Pole Structure: Provides full protection and switching for two separate DC sources (each 2‑pole).
Rated Current Options: Available (commonly) at 63 A and potentially other ratings depending on model.
DIN‑Rail Mountable: Compact design fits standard 35 mm DIN rails in PV combiner boxes and DC distribution panels.
4-Pole Surge Protection Device (SPD) – Designed to protect three-phase AC systems plus neutral from voltage surges and transient over voltages.
High Surge Current Handling – Built to absorb surge currents (typically around 20 kA–40 kA depending on rating) to protect equipment from lightning strikes and switching transients.
Designed for Low-Voltage AC Networks – Works with 230/400 V AC at 50/60 Hz, making it suitable for residential, commercial, and light industrial electrical panels.
Fast Response & Low Let-Through Voltage – Quickly clamps and diverts excess surge energy to ground, reducing the risk of damage to sensitive electronics.
DIN-Rail Mountable – Compact, DIN-rail design for easy installation in distribution boards and sub-panels.
Thermal Disconnect Protection – Often includes thermal disconnection mechanisms for added safety if internal components overheat.
Visual Status Indicators – Many models use simple status windows/LEDs (green for normal, red for fault) to show device health and when replacement is needed.
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.
