MIRO RGS4 75A 690V aR High Speed Semiconductor Fuse, Fast-Acting Protection - Pack of 10

The MIRO RGS4 series is a high-performance semiconductor protection fuse specifically engineered for the ultra-fast clearing of short-circuits. Rated at 75 Amps and 690 Volts, this "aR" utilization category fuse is designed to provide primary protection for power semiconductors such as diodes, thyristors, and IGBTs. The RGS4 fuse minimizes the let-through energy (I²t) during a fault, preventing damage to sensitive electronic components in industrial power conversion systems.

Key Features

• High-Speed Response: Optimized "aR" characteristic provides ultra-fast clearing of faults, essential for protecting delicate semiconductor junctions.
• High Breaking Capacity: Engineered to safely interrupt high fault currents up to 100kA, ensuring system integrity under severe electrical stress.
• Excellent Thermal Stability: Constructed with high-grade materials to ensure low power loss and reliable performance during continuous operation.
• Versatile Industrial Application: Ideal for use in frequency converters, UPS systems, soft starters, and DC drives.
• Robust Construction: Features a durable ceramic body and silver-plated contact surfaces for superior electrical conductivity and oxidation resistance.
