Schneider Electric BLRCH276A331B69 VarPlus Can HDuty 27.6 kvar 690 V 50 Hz Power Factor Correction Capacitor

The Schneider Electric BLRCH276A331B69 is a VarPlus Can HDuty power factor correction capacitor rated 27.6 kvar at 690 V, 50 Hz (33.1 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 clamptite terminal in a 136 mm diameter, IP20 enclosure weighing 3.2 kg.

Selection Notes

HDuty (heavy duty) construction gives the BLRCH276A331B69 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 690 V the unit delivers 27.6 kvar on a 50 Hz network or 33.1 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 136 mm x 242 mm can and clamptite terminal keep the footprint compact for panel-mounted power factor correction banks.
