MIRO RT16-00 NT00 aR Semiconductor Protection Fuse, 63A, 500V

The MIRO RT16-00 NT00 aR fuse is a DIN 43620 size 00 ultra-fast semiconductor protection fuse engineered for safeguarding sensitive power semiconductor devices — including thyristors, diodes, IGBT modules, and rectifier circuits — against short-circuit overcurrents in industrial drive systems, UPS units, and power converters. Rated at 63A with a 500/690V AC voltage class, this aR fuse delivers the extremely low I²t let-through energy and rapid arc extinction required for effective semiconductor protection in demanding B2B applications such as motor drives, frequency inverters, and DC power supplies. Featuring standard NT00 blade-contact dimensions (78mm overall length, 49mm center-to-center mounting), the RT16-00 integrates directly into NH fuse-switch-disconnectors and fuse bases compliant with IEC 60269-4, ensuring straightforward procurement and replacement across European and Asian industrial installations.
