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.
