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.
