Definition: | current coordinate of the intersection between the maximum break-time–current characteristics of two overcurrent protective devices Note 1 to entry: The take-over current is a limiting value of current above which, in the presence of two overcurrent protective devices in series, the protective device generally, but not necessarily, on the supply side, provides back-up operation for the other protective device. Note 2 to entry: I2t characteristics can be used instead of time–current characteristics.
