Selection Notes

At 400/5 A this kit sits mid-range in the ZLBM123 CT family; pick the 200/5 version instead if the switch is lightly loaded, since an undersized secondary current from an oversized ratio reduces meter accuracy near the low end of the scale. The class 1 accuracy is adequate for billing-grade panel ammeters but not for differential protection schemes, which need a protection-class CT.
