STP T12 25 is the series of combined Type 1+2/Class I+II devices for discharging lightning currents and protecting against voltage surges, in accordance with EN/IEC 61643. Suitable as the first step of protection in incoming power supply panels and areas with exposure to the atmosphere, where installations are usually provided with an external lightning protection system. Features
Lightning impulse current (10/350?s): 25kA per phase
Maximum discharge current (8/20?s): 100kA per phase
Nominal discharge current (8/20?s): 25kA per phase
TNS, TNC and TT networks
Un(L-N/L-L): 230/400V
DIN-rail mountable, plug-in format
Visual and remote end of life indicators
Reversible chassis to allow cable entry from above or below
Mechanically coded cartridges to avoid cartridge replacement errors
Back-up fuse: 315 A gG
Applications
Industry and automation
Commercial and residential installations
Telecom & IT & Data Centers
Water treatment
Smart grid & LV Metering
Photovoltaic & wind
