Key Specifications Parameter Category Specification Product Type AC Line Choke (Input Reactor / Supply Inductor) ABB Series / Model ALCL-15-7 Rated Current 15 A (at 40°C ambient, with appropriate derating at higher temperatures) Inductance per Phase 0.70 mH (700 µH) ± 10% (measured at rated current and frequency, e.g., 50/60 Hz) Voltage Drop Typically 3-5% of the supply voltage at rated current (exact value depends on supply voltage). Electrical Connection 3-phase (for connection to 3-phase supply lines L1, L2, L3). Typical Application To be installed on the input (line) side of a VFD with a compatible current rating (e.g., for a drive with an input current of approximately 15A or less, with appropriate safety margin). Key Functions • Harmonic Mitigation: Reduces line-side current harmonics (THDi). • Peak Current Limiting: Limits inrush current. • Transient Protection: Attenuates voltage spikes and line disturbances. • Improves Power Factor: Can improve the displacement power factor. Mounting Typically designed for cabinet or panel mounting via fixing brackets. Insulation Class Standard class (e.g., Class F or H for high-temperature endurance). Core Material Iron core with air gap to prevent saturation.
