Suntree SQ3 2P 40A DIN Rail ATS — Intelligent Automatic Power Transfer for Reliable Uninterrupted Power Supply
Eliminate power interruptions and protect your electrical loads with the Suntree SQ3 2-Pole 40 Amp DIN Rail Automatic Transfer Switch (ATS) — a compact, intelligent, and high-performance switching device engineered to automatically transfer electrical loads between two power sources without manual intervention. Whether switching between the national grid and a generator, solar inverter and grid, or primary and backup power supply, the Suntree SQ3 ATS ensures your critical loads remain powered at all times with zero downtime.
Trusted by electricians, solar installers, facility managers, and system integrators across Kenya and beyond, the Suntree SQ3 2P 40A DIN Rail ATS is the smart, reliable, and cost-effective solution for seamless automatic power source management in residential, commercial, and industrial installations.
Key Features
- 2-Pole (2P) Design: Simultaneous switching of both live and neutral conductors for complete circuit transfer
- 40 Amp Rated Current: Handles substantial loads across residential and light commercial applications
- Automatic Transfer Switching: Instantly detects power source failure and switches to backup supply without manual operation

Why Choose the Suntree SQ3 2P 40A DIN Rail ATS?
Power outages, grid failures, and load shedding are daily realities for homes and businesses across Kenya — and every second of downtime costs money, productivity, and comfort. Manual generator or inverter changeover is slow, inconvenient, and risks equipment damage from delayed switching. The Suntree SQ3 ATS solves this problem permanently.
The moment the primary power source fails or drops below acceptable voltage levels, the Suntree SQ3 automatically detects the failure and transfers the load to the backup source in milliseconds — before you even notice the outage. When primary power is restored, the ATS automatically switches back, ensuring your system always runs on the most preferred and stable power source available.
Its 2-pole DIN rail design makes it the perfect fit for installation directly inside your existing distribution board — no external enclosures, no complex wiring, and no additional hardware required. The 40A current rating gives it the capacity to handle complete household circuits, office floor loads, and light commercial applications with ease.
For solar installations, the Suntree SQ3 ATS plays a critical role in hybrid system design — automatically switching loads to solar inverter output when available, and falling back to grid or generator when solar power is insufficient. This maximises solar self-consumption while ensuring continuous power supply regardless of weather or time of day.
