Square D PFCD4005RF Power Factor Correction Capacitor

The Square D PFCD4005RF Power Factor Correction Capacitor is a NEMA 3R enclosure unit with a 15-amp fuse, designed to supply corrective reactive power in electrical systems where improved power factor is desired. Identified by the PFCD4005RF part number, this Square D device is a dedicated power factor correction capacitor that provides rugged protection and reliable performance in environments requiring weather resistance and overcurrent protection. In practical terms, power factor correction capacitors help balance voltage and current by supplying leading reactive power to offset inductive loads, which can reduce wasted energy and help maintain stable operation under varying load conditions. As a Square D product, the PFCD4005RF aligns with other Square D or Schneider Electric components, offering a consistent option for installations that require a labeled PF correction device within a NEMA 3R enclosure.
