The DS250VG-690 AC surge protector is designed for 3-phase 690VAC and mainly use for wind generator networks. The `Spark gap + Varistor` technology allows a very low level of protection and an absence of following current. The DS250VG-690 is mounted on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network. These AC surge protectors are designed to be connected in multi-pole configuration to protect single-phase, and 3-phase.
