Our Raychem RSTI-SA Dead Break Screened Surge Arresters are designed for direct connection onto outer cone bushings in accordance with EN50180 or EN50181 with interface type “C”. Use them also for parallel connection or mating to the rear entry of the base of the screened connector system designed for voltages up to 41 kV. It features an easily accessible rear plug with a capacitive test point. The insulation of the Dead Break Screened Surge Arrester is made of a highly modified silicone rubber characterized by high tracking resistance, elongation at break and non-flammability. A thin-walled screen is permanently bonded onto the insulation and protects the connection system against unintentional contact.

The active part is a metal oxide arrester that meets the requirements of IEC-60099-4 for separable and dead-front arresters. The combination of screened connector and surge arrester exceeds CENELEC HD 629.1 S2 requirements, which includes BS, VDE and other international specifications. Few accessories are required for system test and earth connection and the complete kit includes the screened surge arrester, threaded pin and ground lead for three phases to facilitate installation and storage.
