Schneider Electric BLRCH417A500B40 VarPlus Can HDuty 41.7/50 kvar 400 V Power Factor Correction Capacitor

The Schneider Electric BLRCH417A500B40 is a VarPlus Can HDuty power factor correction capacitor rated 41.7 kvar at 400 V, 50 Hz (50 kvar at 60 Hz). Its heavy-duty dielectric tolerates network harmonic content up to 20 % and a continuous overcurrent capacity of 1.8 x In, so it keeps correcting power factor on busbars that also feed variable-speed drives, rectifiers and other harmonic-generating loads without overheating.

Selection Notes

At 41.7 kvar and 400 V, the BLRCH417A500B40 is sized for incomers or filter branches with documented harmonic distortion up to 20% - its 1.8 x In continuous overcurrent capacity and 250 x In inrush rating are built in for duty where variable-speed drives or rectifiers already share the busbar. Pick a smaller HDuty step in the same 400 V family when correcting a lighter non-linear load, or a larger one as the reactive power demand grows. On network segments that stay under 10% harmonic content, the standard-duty EasyLogic range covers the same kvar steps at a lower continuous overcurrent rating.
