    • An electronic self-supplied protection device for automatic circuit-breakers that includes: a supply device that draws energy from the stretch of electrical network protected by said circuit-breaker; a control device with at least two levels of operation, where the first of the at least two levels of operation being associated to the function of protection from instantaneous short-circuit SCinst. In addition, second and possible further levels of operation of the self-supplied protection device are associated with further functions of said protection device; a selective interface device including means for regulating the supply, which, in a first step, immediately following upon closing of the circuit by the circuit-breaker, supply the first level of operation, and, after a controlled period of time, supply also the second and possible further levels of operation of said control device.
    • 一种用于自动断路器的电子自供电保护装置,包括:供电装置,其从由所述断路器保护的电网延伸部分吸取能量; 具有至少两个操作级别的控制装置,其中所述至少两个操作级别中的第一级与防止瞬时短路SCinst的功能相关联。 此外,自供应保护装置的第二和可能的进一步的操作水平与所述保护装置的其他功能相关联; 选择性接口装置,包括用于调节电源的装置,在第一步骤中,通过断路器关闭电路之后,提供第一级别的操作,并且在受控的时间段之后还提供 所述控制装置的第二和可能的进一步操作水平。
