Delta Connected Surge Diverter 3P+PE, Nominal voltage 400VAC. Maximum continuous voltage 480VAC & 670VDC. Maximum discharge current (8/20 µs) 200kA (L-PE), Lightning impulse current (10/350 µs) 25kA (L-PE). Nominal discharge current (8/20 µs) 80kA (L-PE). Voltage protection level (In) <1500V (L-PE). The design utilizes metal oxide varistors (MOVs) between phases and a hybrid MOV + gas discharge tube
(GDT) between phase and earth. Designed for protecting delta-connected systems and is ideal for installing in main switchboards.
