STM T23 SF is the series of robust 10kV/10kA combined Type 2+3/Class II+III devices for discharging voltage surges while providing a very fine voltage protection level, in accordance with EN/IEC 61643. Suitable for protection in the fusebox (mast) of LED outdoor luminaires. Due to the exposure of the extremely sensitive LED electronics to lightninginduced overvoltages, STM T23 SF is a widespread market solution amongst OEM manufacturers of LED lighting systems. Features
Maximum discharge current (8/20?s): 10kA
Nominal discharge current (8/20?s): 5kA
Combined discharge pulse (1.2/50?s): 10kV
Single phase networks
DIN-rail mountable, monobloc format
Special size for DIN-rail luminaire fuseboxes
Visual (LED) end of life indicator
Rated current load (IL): 2.5 A
Surge tested and certified luminary with STM T23 SF by accredited lab
Back-up fuse: 25 A gG
Applications
