ATS 400V 125A 3p Automatic Transfer Switch DIN Rail Dual Power Changeover for Solar City Power Generator Uninterrupted

High-Capacity 3-Phase Automatic Transfer Switch - Seamless Backup Power for Industrial & Commercial Systems

• 125A 3-Pole (3P) Design: Handles heavy three-phase loads up to 125A - ideal for factories, commercial buildings, and large solar installations.

• 400V AC Rated: Perfect for European, Asian, and global three-phase grids (230/400V 50/60Hz).

• DIN Rail Mount: Standard 35mm rail mounting - fits neatly into distribution boards and control panels.

• Dual Power Changeover: Automatically switches between Utility Grid, Solar Inverter, and Backup Generator.

• Uninterrupted Operation: Seamless transfer ensures critical equipment stays powered during outages.

• Adjustable Delays: Configurable transfer and return delays prevent nuisance switching.
  
  

  Uninterrupted power is critical for industrial facilities, commercial buildings, and large-scale solar systems. When the grid fails, your backup generator or solar battery must take over instantly. The ATS 400V 125A 3P Automatic Transfer Switch is the robust, reliable solution for managing three-phase power sources.

  Rated for 125 Amps at 400V three-phase, this automatic transfer switch (ATS) continuously monitors your primary power source (e.g., utility grid). If a failure is detected - undervoltage, overvoltage, or phase loss - it automatically transfers the load to your secondary source (generator or solar inverter). When primary power is restored, it switches back.

  Designed for DIN rail mounting, it integrates seamlessly into standard distribution boards and control panels. The 3-pole (3P) configuration switches all three phases (L1, L2, L3), making it suitable for three-phase systems where neutral is not switched (common in TN-C or industrial setups). For applications requiring neutral switching, see our 4P model.

  Perfect for:

• Industrial facilities and factories

• Commercial buildings and data centers

• Large solar PV systems with battery backup

• Hospitals and critical infrastructure

• Agricultural operations and pumping stations
