DACN1-25VGS-10-760

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.

INSTALLATION

DACN1-25VGS-10-760 Type 1+2+3 AC surge protector - 1 pole is connected in parallel on the AC network and must be equipped with external fuses for short-circuit current protection

The total length of parallel connection wires to AC network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
Wiring is made by screw connections.
The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel. Paralleling the protection wire with phases conductors must be avoided.
The cross sectional wire must be 6 mm² minimum for Type 2 SPD and 16 mm² for Type 1.
Local earthing resistance must be in compliance with the electrical rules.
