690V High Speed Square Body Fuse for Semiconductor Protection

Galaxy Fuse (Yinrong) is a premier China manufacturer of the YRSA1-G 690V series high-speed square body fuses, recognized as a key supplier in the nation's semiconductor protection sector.

The 690V High Speed Square Body Fuse for Semiconductor Protection is purpose-engineered to safeguard sensitive power semiconductors including IGBTs and diodes, delivering both short-circuit and overload protection where it matters most. With a rated voltage of 690VAC, the series covers a broad amperage range from 200A to 800A, ensuring compatibility with the vast majority of power conversion equipment and semiconductor devices on the market.

These aR-class fuses feature extremely low I²t values and strong current-limiting capability, minimizing thermal and dynamic stress on protected components during fault conditions, while achieving a robust breaking capacity of 200kA at 690V. The product fully conforms to both the Chinese national standard GB/T13539.4 and the international IEC standard IEC60269-4.

Designed with a compact square body format, the YRSA1-G series optimizes panel space utilization without compromising performance. Beyond the standard offering, Galaxy Fuse (Yinrong) provides extensive customization options, including specialized terminal configurations and visual trip-indicator variants to suit diverse installation requirements.

Every production batch of the YRSA1-G 690V series undergoes rigorous in-house quality assurance, encompassing precision melt etching, homogeneous sand filling, and factory aging tests — all backed by our ISO 9001:2015-certified manufacturing facility and decades of field-proven experience across energy storage, electric vehicle traction, and renewable energy systems.

Choose the YRSA1-G 690V series for demonstrated engineering expertise, internationally recognized certifications, and a dependable long-term partnership.
