Type 1+2+3 AC surge protector - 3-phase+N

DUT250VG-300/G
Part Number 3414
DUT250VG-300/G
  • Type 1+2+3, 3-phase surge protector
  • Common and differential mode
  • Very compact monobloc enclosure
  • Iimp by pole/total : 25kA
  • Internal disconnection, status indicator
  • Optimized to TOV
  • EN 61643-11, IEC 61643-11 and UL1449 ed.5 compliance

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.
