Key features & benefits

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 lightning–induced overvoltages, STM T23 SF is a widespread market solution amongst OEM manufacturers of LED lighting systems.
