Sinofuse RSZ307-01-QKL Fuse, 630A 750V, High-Speed Semiconductor Protection - Pack of 6

The Sinofuse RSZ307-01-QKL is a high-performance, high-speed semiconductor fuse designed by Xi'an Sinofuse Electric. Engineered for the demanding requirements of power electronics and electric vehicle (EV) infrastructure, this fuse provides exceptional protection against overcurrent and short-circuit faults. With a robust 630A rating and 750V capability, it is optimized for high-power DC applications, weight-sensitive environments, and systems requiring high breaking capacity.

Key Features

• High-Speed Interruption: Specifically engineered as a semiconductor protection fuse to provide ultra-fast response times, minimizing the energy let-through (I²t) and protecting sensitive components like IGBTs and thyristors.
• Enhanced Thermal Management: Constructed with high-purity materials to ensure low temperature rise and minimal power loss during continuous full-load operation.
• Vibration and Shock Resistance: Built to meet industrial and automotive-grade standards, ensuring mechanical integrity in mobile or high-vibration environments such as Energy Storage Systems (ESS) and EV charging stations.
• Superior Breaking Capacity: Designed to safely extinguish high-energy arcs, providing reliable circuit isolation even under severe fault conditions.
• Compact Bolted Design: The RSZ307 series features a specialized form factor for secure bolted installation, ensuring low-resistance electrical paths and consistent performance over the product lifecycle.
