    surge protection  DINsafe - SDD3 Surge Diverters
    Product Features
    Compliant with the relevant IEC lightning and surge protection standards, in particular IEC 62305 and IEC 61643. All Mode Protection - Novaris models featuring all mode protection provide protection for all combinations of lines (L-N, L-E, N-E) ensuring the maximum level of protection is achieved at all times. They have been designed for installation in any wiring system worldwide. Thermal Sensing - Sustained overvoltages can cause components to overheat and degrade. LED Status Display - LED indicators are provided on models to indicate operating status. External Alarms - Models featuring external alarms have voltage free changeover contacts for remote status indication. DIN 43880 Compliant - Protection devices housed in DIN 43880 compliant enclosures allow for convenient installation on DIN rail fittings commonly used in switchboards worldwide. Safe Metal Enclosure - Novaris surge protection products are housed in safe, all metal enclosures. In the event of a prolonged overvoltage they will not catch fire or explode.
