TDK EPCOS B25673A4252A040 PhaseCap Compact Capacitor, 25kvar 440V, MKK440-D-25-02

The TDK EPCOS B25673A4252A040 is a high-performance power factor correction (PFC) capacitor from the PhaseCap Compact series. Detailed under the type designation MKK440-D-25-02, this three-phase, delta-connected unit is designed for industrial applications requiring robust reactive power compensation. Utilizing self-healing polypropylene film technology and a non-PCB, semi-dry biodegradable resin, it offers high operational safety and a mean life expectancy of up to 200,000 hours under specific temperature classes.

The capacitor is housed in an extruded round aluminum can featuring an overpressure disconnector to ensure safe failure at the end of its service life. Its design includes optimized safety terminals (IP20) and a ceramic discharge module. This unit is specifically engineered for indoor mounting with natural or forced air cooling, providing stable performance in power quality management systems.

Main Features:

• Construction: Metalized polypropylene film with concentric winding and wave cut for superior durability.
• Safety System: Integrated overpressure disconnector and self-healing technology.
• Efficiency: Very low dielectric losses (approx. 0.2 W/kvar).
• Installation: Bottom-mounted M12 threaded stud for secure fixing and grounding.
• Standards: Compliant with IEC 60831-1/2 and UL 810-5th edition.
