The 825 Plus core balance/ground fault current transformer (GFCT) input has an operating range of 5 to 500 mA. Care is required to ensure

this input range is not exceeded. When existing CT has a ratio of 50:0.025 (2000:1), the minimum trip level is 10A primary. For lower trip
levels, the core balance/GFCT will need to be replaced with a 100:1 ratio CT. Refer to the catalog number breakdown for part numbers of
various donut CT window sizes.
