MIRO RS33 NGTC2 High-Speed Semiconductor Fuse, 250A 690V, aR Square Body NH2 Size - Pack of 6

The MIRO RS33 NGTC2 is a high-performance, high-speed semiconductor fuse designed for the protection of power electronic devices. Rated at 250 Amps and 690 Volts, this fuse belongs to the NH2 (NGTC2) size category and features a blade-style mounting (square body) commonly used in industrial power distribution panels. The RS33 series is specifically engineered with an "aR" utilization category, providing ultra-fast clearing characteristics to protect components like thyristors, diodes, and larger power converters from overcurrent and short-circuit faults.

Key Features

• Semiconductor Grade Protection: Utilization category "aR" ensures localized, high-speed protection by minimizing let-through energy (I²t) during fault conditions.
• Standardized NH2/NGTC2 Design: Conforms to standard industrial dimensions for easy integration into existing fuse bases and switch-disconnectors.
• High Breaking Capacity: Capable of safely interrupting massive fault currents, ensuring the safety of personnel and expensive downstream equipment.
• Superior Heat Dissipation: Constructed with a high-strength ceramic body and silver-plated copper contacts to ensure low power loss and efficient thermal management.
• Reliable Industrial Mounting: The blade-type (knife-edge) design provides a secure and low-resistance electrical connection suitable for high-vibration industrial environments.
