PhaseCap Compact Power Factor Correction Capacitor
When panel space is constrained and a compact cylindrical capacitor is needed for automatic PFC banks — PhaseCap Compact is what we specify. With diameters of only 116 and 136mm it fits in space-saving enclosures while delivering up to 33 kVAr and tolerating inrush currents up to 400 times rated current.
About this product
PhaseCap Compact is EPCOS/TDK's space-optimised cylindrical capacitor for automatic power factor correction banks where panel space is the primary constraint. With housing diameters of only 116mm and 136mm, PhaseCap Compact allows significantly higher capacitor density in the same panel enclosure volume — critical for retrofit PFC installations where the existing panel cabinet cannot be enlarged and for new designs in tight spaces such as switchgear-integrated PFC modules. Despite its compact dimensions, PhaseCap Compact maintains full performance specifications including self-healing MKK film technology, inrush current tolerance up to 400 times rated current for compatibility with C24 capacitor duty contactors, and outputs up to 33 kVAr per unit. Both gas-filled and resin-impregnated versions are available covering voltage ranges from 230V to 1000V, compatible with standard European LV network voltages and high-efficiency drive system bus voltages. Typical applications include PFC retrofit projects in existing LV switchboards where additional capacitor volume cannot be accommodated in the original enclosure, switchgear-integrated PFC compartments where overall panel depth is constrained, and new PFC panel designs targeting minimum footprint for space-constrained plant rooms or data centre electrical rooms.
