IEC 61643-341 Testing
Components for low-voltage surge protective devices – Part 341: Specification for thyristor surge suppressors (TSS)
IEC 61643-341 Scope:
IEC 61643 341 and EN 61643 341 testing is for thyristor surge suppression (TSS) components designed to limit overvoltages and divert surge currents by clipping and crowbarring actions. Such components are used in the construction of surge protective devices, particularly as they apply to telecommunications.
IEC 61643-341 tests contain information on:
- Terms, letter symbols, and definitions
- Basic functions, configurations, and component structure
- Service conditions and fault modes
- Rating verification and characteristic measurement
