2 Pole 63A/125A ATS Automatic Transfer Switch, PV Rated 230V 50/60Hz, Manual Auto Mode, Dual Power Changeover for Solar System & Generator Backup
Compact 2P ATS for Solar & Backup Power - 63A/125A, Manual/Auto, DIN Rail
Dual Power Changeover: Automatically or manually switches between Mains (Grid) and Generator/Solar Inverter.
2-Pole (2P) Design: Switches Live (L) and Neutral (N) - complete isolation for single-phase systems.
63A or 125A Capacity: Choose the right rating for residential solar or light commercial backup.
Manual/Auto Operation: Selector switch lets you choose automatic transfer or manual override.
MCB Style Form Factor: Compact, mini circuit breaker appearance - fits neatly in distribution boards alongside standard breakers.
DIN Rail Mount: Snaps onto 35mm rail - easy installation in PV combiner panels or home consumer units.
Wide Voltage & Frequency: 230V AC, 50/60Hz - suitable for global single-phase grids.
Solar PV systems with battery backup or generator backup need a reliable way to switch between the utility grid and the alternative source. The 2P Dual Power Automatic Transfer Switch (ATS) is designed specifically for single-phase solar installations, providing automatic or manual changeover in a compact, MCB-style DIN rail package.
Available in 63A or 125A versions (230V AC, 50/60Hz), this 2-pole (2P) ATS switches both Live and Neutral - ensuring complete isolation for safety and code compliance. The front-panel selector allows you to choose:
Auto Mode: The ATS monitors the mains voltage and automatically transfers to backup when the grid fails, then returns when power is restored.
Manual Mode: You manually select which source (Mains or Backup) powers your load - ideal for testing or maintenance.
The miniature circuit breaker style housing saves valuable panel space and blends seamlessly with other DIN rail devices. With its built-in mechanical interlock, it is physically impossible to connect both sources simultaneously - preventing dangerous backfeed.
Ideal for:
Residential solar + battery systems (islanding backup).
Portable generator backup for homes, workshops, or off-grid cabins.
Small commercial PV with generator fallback.
Any single-phase application requiring automatic or manual dual power changeover.
Frequently Asked Questions
What is the primary function of the 2P Dual Power Automatic Transfer Switch?
It automatically or manually switches your electrical load between the Mains (utility grid) and an alternative generator or solar inverter source to ensure continuous power.
Does this 2-Pole (2P) design switch both Live and Neutral lines?
Yes, the 2-Pole design switches both the Live (L) and Neutral (N) lines simultaneously, providing complete isolation for single-phase power systems to ensure safety.
What is the difference between Auto and Manual modes?
In Auto Mode, the device monitors the grid and switches to backup automatically if grid power fails. In Manual Mode, you can manually select the active power supply source via the front selector switch.
Is it safe from backfeed issues?
Yes, this transfer switch is equipped with a built-in mechanical interlock mechanism that physically prevents connecting both power sources at the same time.
How is this product installed in a breaker panel?
The unit has a compact MCB-style form factor designed to snap onto a standard 35mm DIN rail, making it easy to install in distribution boards.
