Compact Capacitor

MKK400-D-25-02 is a three-phase film capacitor from the EPCOS/TDK PhaseCap® Compact series, designed for power factor correction (PFC) in industrial and commercial electrical systems. 

It is rated for 25 kvar output at 400 V AC (30 kvar at 60 Hz), with a delta (D) connection. 

The capacitor features self-healing metallized polypropylene film technology, concentric winding, and a semi-dry biodegradable resin impregnation for enhanced reliability and longevity. 

It is housed in a compact extruded aluminum can with a threaded M12 bolt for mounting, suitable for indoor installation in any position. 

The device is maintenance-free, includes a ceramic discharge module and overpressure disconnector for safety, and complies with IEC 60831-1/2 and UL 810 standards. Typical applications include capacitor banks and automatic PFC equipment for improved energy efficiency and power quality.
