Abstract
An overcurrent and/or short-circuit detector includes: at least one current sensor for picking up a current signal which has a predeterminable time resolution in at least one electrical current path; and at least one evaluation unit. The at least one evaluation unit: determines a first point in time of a predeterminable steep increase in the current signal, forms a temporal integral of current values of the current signal from the first point in time to a second point in time, compares a pair of values, including a relevant value of the integral and the relevant value of the current signal, with at least one predeterminable limiting condition at predeterminable temporal intervals substantially continuously, and emits an overcurrent and/or short-circuit signal to an outlet of the overcurrent and/or short-circuit detector if the pair of values exceeds a limiting condition.
