The Siemens 3NE87271 SITOR Semiconductor Fuse Link is a premium high-speed protection device specifically designed to safeguard semiconductor components against short-circuit faults and excessive fault currents. Part of the trusted Siemens SITOR 3NE8 Series, this fuse delivers ultra-fast response characteristics that help protect valuable power electronic equipment such as inverters, converters, UPS systems, soft starters, rectifiers, and variable frequency drives (VFDs). The fuse features a 250A rated current, 690V AC operating voltage, 700V DC capability, and aR operating class, making it ideal for semiconductor protection applications.
Available through SB Smart, the Siemens 3NE87271 is engineered to provide reliable fault interruption, reduced let-through energy, and enhanced protection for modern industrial power electronics systems.
Unlike standard line-protection fuses, semiconductor fuses must react extremely quickly to protect sensitive devices such as:
The Siemens 3NE87271 utilizes aR characteristic protection, specifically developed for semiconductor circuits. Its ultra-fast operating behavior helps minimize thermal and electrical stress during fault conditions, reducing the risk of costly equipment damage and downtime.
The 3NE87271 features an NH000 fuse size with bolt-on silver-plated connections that ensure reliable electrical contact and secure installation. The fuse also includes a front indicator, allowing maintenance personnel to quickly identify a blown fuse and simplify troubleshooting procedures.
Key performance characteristics include:
The Siemens 3NE87271 Semiconductor Fuse is suitable for:
