Features:

• 11 kV to 400 V conversion : Converts medium-voltage electricity into low-voltage power for buildings, factories, and equipment.
• High efficiency
• Natural cooling — ONAN: Uses natural circulation of oil and air for cooling, without cooling fans or pumps.
• Operation up to +45°C ambient: Designed for hot conditions within the stated rating. Correct ventilation and installation remain essential.
• C5 corrosion protection: for harsh or coastal environments.
• Dyn11 connection: A common three-phase distribution configuration, with a neutral connection on the low-voltage side.
