Combined surge arrester 5SD741 series

type 2type 1for electrical installations

Every year, several hundred thousand cases of damage from lightning strikes and overvoltages are reported in Germany alone, with resulting costs in the multi-million euro range. Play it safe – with overvoltage protection devices from our SENTRON portfolio! These devices are part of a comprehensive protection concept for electrical installations, and reliably prevent damage from  overvoltage. • Compact designs that can be used as both lightning arrester (type 1) as well as surge arrester (type 2) • Protects low-voltage systems against overvoltage triggered by lightning strikes or grid switching operations • Thermal isolating arrester disconnector offers a high level of protection against overload Overvoltages are brief voltage peaks of less than a thousandth of a second that exceed by many times the allowable design operating voltage of electric devices.
