The Atman TRF 3000 VA is a three-phase open-type isolation transformer with a 230V/230V ratio, rated for continuous duty in air under normal ambient conditions. It is designed for industrial and technical installations that require reliable galvanic separation between three-phase circuits.

An isolation voltage of 3750V AC and insulation class ratings of B, F, and H meet demanding electrical isolation standards. The Class I safety classification and 300×200×140mm housing allow integration into industrial panels and large enclosures.
