Surge-Trap® Pluggable STPT12 Series - AC Reinforced
Surge-Trap® Pluggable STPT12 Series - AC-Reinforced is the series of combined Type 1+2/Class I+II devices intended for discharging lightning currents (10/350 μs) and protecting against induced voltage surges (8/20 μs), in accordance with IEC/EN 61643-11 . Suitable for the AC side protection of inverters or wind turbine generators with a nominal voltage of 800 V AC. The reinforced 3+1 variant ensures safe operation where high withstand voltage peaks are required or where DC offsets are induced in AC side.
