690V High Breaking Capacity Semiconductor Fuse

Galaxy Fuse (Yinrong) is a professional supplier of the 690V High Breaking Capacity Semiconductor Fuse, a product series dedicated to protecting AC 690V power conversion equipment including inverters, drives, and semiconductor devices. This series is designed to deliver reliable overcurrent and short-circuit protection under the most demanding industrial conditions, where system uptime and component safety are paramount.

The 690V High Breaking Capacity Semiconductor Fuse covers a continuous current spectrum from 40A to 630A, accommodating a diverse range of power stages. With its aR usage category, this fuse ensures extremely fast response to fault currents, minimizing energy let-through and reducing thermal stress on sensitive IGBTs and thyristors. Its outstanding 200kA breaking capacity at 690V AC—among the highest in its class—guarantees safe and reliable interruption even under severe short-circuit events, providing an exceptional safety margin for system designers.

This product line strictly conforms to both the international IEC60269-4 and the Chinese GB/T13539.4 standards, and carries CE certification for European market acceptance. The series is available in multiple ampere ratings with clearly specified pre-arcing and total clearing I²t values, enabling precise coordination with upstream and downstream protection devices. This level of detailed parameterization allows engineers to achieve selective protection schemes with confidence, reducing nuisance tripping while ensuring fault isolation.

Beyond its technical specifications, the 690V High Breaking Capacity Semiconductor Fuse is built with robust construction featuring M8 stud terminals for secure and low-resistance connections. Yinrong provides complete technical documentation including time-current characteristics and current-limiting curves, facilitating accurate system design. Each production lot undergoes rigorous quality assurance procedures—including element precision etching, homogeneous arc-quenching media filling, and comprehensive factory testing—backed by our ISO 9001:2015-certified manufacturing facility and extensive field experience in metallurgy, renewable energy, and rail transit applications. Choosing the 690V High Breaking Capacity Semiconductor Fuse means prioritizing system safety, protection coordination, and long-term operational reliability.
