A surge protection device is a device that prevents the transmission of lightning to electrical equipment. The task of this device is to limit and minimize the influence of lightning on surrounding electrical equipment along power lines, signal lines, and metal wires.

STMT23-20KA SLIM SERIES is the series of combined Type 2+3/Class II+III devices for discharging voltage surges while providing a very fine voltage protection level, in accordance with IEC/EN 61643-11. Suitable as the final stage of protection in locations with Type 2 protection devices installed upstream. These SPDs should be installed as close as possible to the equipment being protected. Ideal for limited spaces. Wide range of voltage ratings.
