CHARACTERISTIC CURVES
Figures 1-6 through 1-14 illustrate the characteristic curves that are programmed into the nonvolatile
memory of series 100 relays. Figures 1-6 through 1-19 illustrate the characteristic curves that are
programmed into the nonvolatile memory of series 200 relays. To order full-size drawings of these
characteristic curves, contact Customer Service Department of the Power Systems Group, Basler Electric,
