Reliable switching devices: Use non-restriking, non-bouncing vacuum contactors, vacuum circuit breakers, or SF₆ circuit breakers for automatic capacitor bank switching.
Automatic tracking compensation: The control system detects, evaluates, and tracks to achieve a preset power factor, optimizing voltage and power factor.
Modular cabinet construction: Step-switched automatic compensation devices consist of multiple cabinets made of cold-rolled steel (bent, welded, powder-coated) or aluzinc steel (bent, assembled). Max IP40 protection.
Integrated three-phase design: Dry-type iron-core reactor coils available in aluminum (default) or copper (specify if copper needed).
Overcurrent protection: Step-switched compensation devices can be equipped with CTs for two-stage overcurrent protection of capacitor banks.
