The DAC1-13VG 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 DAC1-13VG is one-pole SPD and can be used in common mode or common and differential mode.
DAC1-13VG 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.
DAC1-13VG-31-275 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
Further information can be found in IEC 61643-12 standard (selection and application principles for low voltage SPD).
