Product Code: SDD3-50-275-A

The Surge Diverter is a 3-phase device designed to protect against voltage surges. It has a nominal voltage of 230 VAC and a maximum continuous voltage of 275 VAC. The maximum discharge current is 50 kA (L-N) and 25 kA (N-PE) at 8/20ms, while the nominal discharge current is 20 kA (L-N) and 10 kA (N-PE) at 8/20 us. The voltage protection level is 1250V (L-N) at the nominal discharge current. This surge diverter features a shunt connection and active alarms. The LED display indicates the phase status and normal operation when all LEDs are lit. It is suitable for use in domestic MSBs and industrial DBs.
