NOVARIS SURGE DIVERTER 3P+N+PE 150kA SDD3-150-275-A

Product Code: SDD3-150-275-A

The Surge Diverter is a 3-phase device designed for domestic MSBs and industrial DBs. It provides protection against voltage surges with a nominal voltage of 230 VAC and a maximum continuous voltage of 275 VAC. The surge diverter has a maximum discharge current of 150kA (L-N) and 60kA (N-PE) at 8/20ms. It offers a voltage protection level of less than 1.25kV (L-N) and less than 1.3kV (N-PE) when operating at its rated current. The surge diverter features a shunt connection and active alarms for monitoring purposes. Its LED display indicates the phase status and normal operation when all LEDs are lit.
