Schneider Electric BLRCH339A407B48 VarPlus Can HDuty 33.9 kvar 480 V 50 Hz Power Factor Correction Capacitor

The Schneider Electric BLRCH339A407B48 is a VarPlus Can HDuty power factor correction capacitor rated 33.9 kvar at 480 V, 50 Hz (40.7 kvar at 60 Hz). Built with a metallized polypropylene film dielectric and a 1.8× In continuous overcurrent rating for networks with up to 20% harmonic content, it connects through a stud terminals in a 116 mm diameter, IP00 enclosure weighing 4.1 kg.

Selection Notes

HDuty (heavy duty) construction gives the BLRCH339A407B48 a 1.8× In continuous overcurrent capacity, so it stays within rating on networks where variable-speed drives or rectifiers push harmonic distortion toward the 20% ceiling — a standard-duty capacitor sized only for the fundamental would overheat under the same load. At 480 V the unit delivers 33.9 kvar on a 50 Hz network or 40.7 kvar on a 60 Hz network from the same can, useful when the same bank design serves both European and North American sites. Pick this variant to match bus voltage directly rather than relying on a transformer tap; the 116 mm x 321 mm can and stud terminals keep the footprint compact for panel-mounted power factor correction banks.
