TOMZN T0Q3-125 Automatic Transfer Switch (125A, 4-Pole)
The TOMZN TOQ3-125 is a 125-amp automatic transfer switch (ATS) that automatically switches power between your main supply (KPLC/grid) and a backup source (generator or inverter).
When the main power fails, it automatically transfers your load to the backup source in milliseconds — ensuring your lights, fridge, or water pump keep running smoothly.
When grid power returns, it switches back to normal supply without needing manual control.
This model is designed for three-phase 4-wire (or single-phase) AC systems, operating at 230V / 400V, making it ideal for both home and commercial installations.

🔌 How It Works
- Connect both Normal Power (KPLC) and Backup Power (Generator/Inverter) inputs.
- Set the switch to Automatic Mode.
- When KPLC power cuts off, it automatically connects your load to the backup source.
- When KPLC returns, it automatically transfers back.
- For maintenance or testing, switch to Manual Mode and control the source yourself.
🏠 Common Uses in Kenya
- Residential Homes: Keep lights, TVs, and fridges on during power cuts.
- Shops & Supermarkets: Maintain power to freezers and billing systems.
- Water Pumps & Boreholes: Prevent interruptions during load-shedding.
- Office Buildings: Ensure computers, routers, and servers remain powered.
- Farms & Industrial Sites: Reliable backup for motors and control systems.
Simple Explanation
Think of the T0Q3-125 as a smart switch that watches your main and backup power lines.
When KPLC power goes off, it automatically moves your load to the generator or inverter — and when the grid returns, it switches back.
This happens in seconds, without you having to do anything.
It’s like having a person standing by your power system 24/7, ready to switch power the moment a blackout happens.
