STMT1-50KA SERIES

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.

STM T1 50 is the most robust series of single pole Type 1/Class I lightning current arresters, able to discharge energy (current) from a direct lightning strike (10/350μs) on an external lightning protection system (LPS) or overhead supplies, in accordance with IEC/EN 61643-11. Suitable as the first step of protection in incoming power supply panels and areas with high exposure to lightning strikes, fitted with an external lightning protection system.
