Benefits


390x195ijjpg
High Performance

The unique 2-pole switch design has been optimized to break mid-currents up to 1500V DC easily and reliably, across the complete lifespan of the installation

Space saving
Fast and Flexible

Modular design provides the advantage of operating more than one 1500V DC circuit simultaneously with a single switch, giving you more alternatives to design your installation
