These capacitors which have been designed especially for harmonic filtering in three-phase mains stand out by their high AC-voltage load capacity and suitability for high rms and surge currents. Thanks to their construction they have a very low series resistance and a low self-inductance.
The three capacitor elements are connected in delta internally; liquid resin filling serves for improved heat dissipation. The finger-proof screw terminals of designs CAPAGRIPTM K, L and M (rated IP20) make for simpler connections.
