Schneider Electric BLRCH075A090B40 VarPlus Can HDuty 7.5/9 kvar 400 V Power Factor Correction Capacitor

The Schneider Electric BLRCH075A090B40 is a VarPlus Can HDuty power factor correction capacitor rated 7.5 kvar at 400 V, 50 Hz (9 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 double faston terminal.

Selection Notes

Match the BLRCH075A090B40 to the switchboard's nominal voltage (400 V) and the reactive power step the correction bank needs -- 7.5 kvar at 50 Hz, 9 kvar at 60 Hz. At 7.5/9 kvar it is the largest step still built on the compact 63 mm can; the next size up (10 kvar and above) moves to the 75 mm ClampTite-terminal can. 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.
