New Original Siemens 3NE1435-0 SITOR FUSE LINK Full Technical Introduction
1. Product Overview
The 3NE1435-0 is an original Siemens SITOR series high-performance semiconductor protection fuse link, categorized as NH3 size LV HRC (High Rupturing Capacity) fuse with gR utilization class. It is specially engineered for full-range protection of power semiconductor components including IGBT modules, rectifiers, inverters, servo drives, DC link circuits, UPS power supplies, soft starters and frequency converters in industrial automation systems.
This fuse adopts a high-temperature ceramic housing with slotted blade contact structure, equipped with a built-in front visual blown indicator for rapid fault identification. It complies with IEC 60269-4 and VDE 0636-4 industrial standards, supports 690V AC and 440V DC rated voltage, and provides precise current limiting performance under short-circuit and overload conditions. Widely applied in packaging machinery, metal processing equipment, wind power converters, solar inverters, logistics automation lines and 3C manufacturing equipment. The new original unit maintains consistent electrical characteristics without parameter drift, meeting RoHS and EU CE certification requirements for global export projects.
2. Main Core Functions
- Full-range gR semiconductor protection: intercepts both overload current and severe short-circuit current to avoid permanent burnout of expensive power semiconductors
- Ultra-fast current limiting cut-off capability, effectively suppress short-circuit energy and reduce secondary damage to peripheral circuit parts
- Integrated front mechanical indicator window; the indicator pops up visibly once the fuse element melts for quick on-site troubleshooting
- High stable load factor, adapts to frequent variable load cycles under continuous 24-hour industrial operation
- Standard NH3 slotted blade contact design, compatible with Siemens matching fuse bases, fuse switch disconnectors and direct busbar bolt mounting
- Low power loss internal melt structure, minimizes heat generation during long-term rated current operation to lower cabinet heat dissipation pressure
- Wide ambient temperature adaptability, stable performance under workshop normal and mild high-temperature working environments
- Single-use disposable protection unit with standardized replacement structure for easy on-site maintenance
- High breaking capacity to withstand extreme short-circuit current in heavy industrial power distribution loops
- Unified Siemens SITOR series dimensional standard, convenient for batch spare parts inventory management
