3 Phase

DS40 type 2 AC Surge Protector used mainly for primary protection of single and 4- phase networks at the main electrical panel. They provide common-mode or common and differential mode. This SPD is based on high energy varistor equipped with thermal disconnector and failure indicator, to comply with standards. The DS40 surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase or 3-phase+Neutral AC networks. They are sometimes associated with dedicated N/PE surge protector based on gas tube technology.

DS40VG Type 2 +3 AC surge protector, using CITEL's 'VG technology', to completely eliminate the leakage and operation current while providing maximum discharge capacity and an optimized level of protection. The electric scheme includes a disconnector and its associated indicator .. The DS40VG surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase or 3-phase+N AC networks.
