The DUT250VG-300/G is a Compact and Heavy Duty Type 1 AC Surge Protector Device (SPD) designed to be connected at the entrance of the electrical installation, on a 3-Phase 230/400V AC network.

This SPD provides an efficient protection against direct and indirect effects and is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (i.e.: buildings equipped with lightning rods or metallic poles, as radio base stations).

The DUT250VG-300/G is a 3-Phase+Neutral SPD and provides a common (L/G) and differential (L/N) mode protection. It complies to the Connection Type 2 configuration following IEC 60364-5-534.

This SPD is designed to withstand 25 kA lightning surge current (10/350 µs impulse). It is based on specific heavy duty GDTs and high energy MOV blocks : this technology allows the best behaviour possible on AC network (no follow current and no leakage current) and a very low residual voltage.

This SPD is built in a compact enclosure for DIN rail mounting.
