CHARACTERISTIC CURVES
Figures 1-7 through 1-15 illustrate the characteristic curves that are programmed into the nonvolatile
memory of series 100 relays. Figures 1-7 through 1-20 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,
and request publication number 9 2520 00 999 (Figures 1-7 through 1-20). These publications contain full
size characteristic curves on transparent paper (vellum).
