NGTC3 RS32 630A 690V aR Fast Fuse - Semiconductor Protection

The NGTC3 (also known as RS32) 630A high-speed fuse is a specialized, high-performance solution engineered for protecting semiconductors and power electronic equipment against short-circuit currents in low-voltage industrial systems.

With rated voltage options of 500V and 690V AC, and exceptional breaking capacities of 120kA (at 500V) and 50kA (at 690V), this aR-class fuse delivers fast, reliable current-limiting protection. Its robust ceramic body and precision-engineered element ensure stable arc quenching and high thermal stability, even in demanding environments.

Designed to meet GB/T13535.4 standards, this square-tube, blade-contact fuse is ideal for use in variable frequency drives (VFDs), inverters, rectifiers, UPS systems, and power converters. It prevents catastrophic damage to sensitive components by interrupting faults within milliseconds, helping you reduce maintenance costs and maximize equipment uptime.

Available in a wide range of ampacities, this fuse is a trusted choice for industrial automation, power distribution, and renewable energy applications.
