Harmonic Block Reactors are designed to reduce harmonic distortion, improve power quality, and protect capacitor banks in electrical systems. Available with filtering factors of 5.6%, 7%, 14%, or custom specifications, they feature a low-loss design, excellent thermal performance, and high overload capability. Built with H-Class insulation, vacuum impregnation, and robust strip-wound construction, these reactors deliver reliable, efficient, and long-lasting performance even in demanding operating conditions.
