The DACN1-25VG is an extreme duty Type 1+2+3 SPD designed to protect AC powerline at the main switchboard of an installation equipped with lightning rod, and in wind turbines' application, the low-voltage side of transformer and power side of convertor is the typical application. Equipped with exclusive CITEL’s VG technology, the range achieves an high protection level, guaranteeing a maximum protection efficiency, a absence of follow and leakage currents, a simplification of use (no additional lightning arrester required) and a maximum lifetime.
