TOMZN TOQ3-125 125 Amp 230/400 Volt Automatic Transfer Switch | Reliable Generator/Inverter ATS

 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.

📋 Technical Specifications

🔌 How It Works

1. Connect both Normal Power (KPLC) and Backup Power (Generator/Inverter) inputs.
2. Set the switch to Automatic Mode.
3. When KPLC power cuts off, it automatically connects your load to the backup source.
4. When KPLC returns, it automatically transfers back.
5. 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.
