The 3XL Three-Phase Common Mode Power Line Choke is designed for high-power industrial EMI suppression applications in three-phase AC power systems. It provides strong common-mode noise attenuation, high current handling capability, and stable long-term electrical performance under demanding operating conditions.
Built with a robust multi-phase magnetic structure, the choke effectively suppresses electromagnetic interference generated by industrial drives, power converters, and heavy-duty electrical equipment.
The 3XL series is optimized for industrial-grade environments where three-phase power systems require reliable EMC performance, high thermal endurance, and stable filtering capability.
Customized inductance values, current ratings, insulation systems, and mounting configurations are available based on application requirements.
