Range Technical Sheet

The DS250VG is an extreme duty Type 1+2+3 AC surge protector device designed to protect at the entrance of the electrical installation. This SPD is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (eg: buildings equipped with lightning rods). The DS250VG is one-pole SPD and can be used in common mode or common and differential mode. DS250VG AC surge protectors are designed to be connected in multi-pole configuration to protect single-phase, 3-phase and 3-phase+Neutral AC networks, sometimes associated with a dedicated N/PE SPD.
