3NE1230-2 SIEMENS SITOR fuse link

SIEMENS 3NE1230-2 SITOR fuse link

Product Description:

The SIEMENS 3NE1230-2 is a high-performance current limiting fuse designed for the reliable protection of semiconductor devices in power electronic applications. This semiconductor protection fuse is specifically engineered to safeguard sensitive components such as diodes, thyristors, and IGBTs in converters, frequency inverters, and soft starters from destructive overcurrents and short-circuit conditions. It features an extremely fast-acting characteristic that quickly interrupts fault currents before they can damage valuable power semiconductors, thereby minimizing downtime and repair costs in industrial power systems.

This fuse employs a specialized design with quartz sand filling that ensures efficient arc extinction and current limitation during fault conditions. The robust ceramic body provides excellent mechanical strength and thermal stability, making it suitable for demanding industrial environments. The fuse is designed for easy installation in standard fuse holders and features an indicating pin that provides clear visual confirmation of fuse operation. Its current-limiting capability significantly reduces the thermal and dynamic stresses on protected equipment, making it an essential component in industrial drives, power supplies, and renewable energy systems where semiconductor reliability is critical.

Technical Specifications Reference:

The SIEMENS 3NE1230-2 is a semiconductor protection fuse with a rated voltage of 690 V AC and a rated current of 200 A. The fuse demonstrates a breaking capacity of 100 kA at 690 V AC, ensuring reliable interruption of high fault currents. It features a very low power loss of approximately 90 W per fuse at rated current, contributing to energy efficiency in the system.

The fuse is designed with a size 00 case according to DIN 43625 standards, facilitating standardized mounting in compatible fuse bases. It employs a time-current characteristic specifically tailored for semiconductor protection, providing very fast clearing times for overcurrent conditions. The operating temperature range extends from -5°C to +55°C ambient temperature, with storage temperatures from -25°C to +70°C. The fuse body is constructed from high-strength ceramic material with corrosion-resistant metal end caps and includes a striker pin mechanism for remote indication of fuse operation. It complies with international standards including IEC 60269-4 and carries relevant certifications for global market acceptance.
