Sinofuse RS309-MD High-Speed Fuse, 60A 500V AC/DC, aR Semiconductor Protection, Bolted Tag - Pack of 10

The Sinofuse RS309-MD is a professional-grade high-speed fuse specifically designed for the protection of power semiconductor devices. Engineered by Xi'an Sinofuse Electric Co., Ltd., this fuse-link features an "aR" utilization category, providing ultra-fast response to overcurrent events. It is a critical component for safeguarding diodes, thyristors, IGBTs, and other sensitive power electronic equipment in both AC and DC circuits.

Key Features

• Dual AC/DC Rating: Versatile application range with a 500V rating for both alternating and direct current systems.
• High Breaking Capacity: Engineered to safely interrupt fault currents up to 200kA in AC circuits and 50kA in DC circuits, preventing catastrophic equipment failure.
• Semiconductor Protection (aR): Ultra-fast acting characteristic ensures minimum energy let-through (I²t), providing superior protection for delicate power electronics.
• Global Standard Compliance: Fully certified under CE, UL (cURus), and RoHS standards, and manufactured according to IEC 60269 requirements for international reliability.
• Robust Bolted Construction: Features a blade-style mounting for secure bolted installation, ensuring stable electrical contact in high-vibration industrial environments.
