Schneider Electric BLRCH144A173B48 VarPlus Can HDuty 14.4/17.3 kvar 480 V Power Factor Correction Capacitor

The Schneider Electric BLRCH144A173B48 is a VarPlus Can HDuty power factor correction capacitor rated 14.4 kvar at 480 V, 50 Hz (17.3 kvar at 60 Hz), built for networks with up to 20% harmonic content where the circulating harmonic current requires an increased rated current capacitor rather than a standard-duty unit. Fastening is by clamptite terminal.

Selection Notes

Match the BLRCH144A173B48 to the switchboard's nominal voltage (480 V) and the reactive power step the correction bank needs -- 14.4 kvar at 50 Hz, 17.3 kvar at 60 Hz. It is the highest reactive-power step in the 480 V HDuty line on the 90 mm can, one size above the 12.5/15 kvar BLRCH125A150B48 at the same voltage and can diameter. The 1.8 x In continuous overcurrent capacity and <=20% permissible network harmonic content make HDuty construction the right choice where variable-speed drives or other non-linear loads circulate harmonic current; on a clean network a VarPlus Can SDuty unit would be the lower-cost alternative.
