The DUT250VG is a compact and heavy duty Type 1+2+3 SPD, designed to be connected at the entrance of the electrical installation, on a 3-phase 230/400 V AC network. The Spark gap + Varistor technology allows a very low level of protection and an absence of following current. The DUT250VG is a 3-phase SPD and provides a common and differential mode protection. This SPD is built in a compact enclosure for DIN rail mounting.

INSTALLATION

DUT250VG-300/G Type 1+2+3 AC surge protector - 3-phase+N are 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. On some models, a distribution bus can be used.
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.

Further information can be found in IEC 61643-12 standard (selection and application principles for low voltage SPD).
