Abstract (en)
[origin: CN112670947A] The invention relates to a protective apparatus of an alternating current electrical installation provided with a compact member comprising a magnetic triggering coil and a triggering relay coil and with an electronic circuit connected to the triggering relay coil, characterized in that said electronic circuit comprises a prolonged overcurrent detector (60) and comprises a switching circuit (61), which are configured such that in the absence of a detection signal the switching circuit connects the triggering relay coil to the prolonged overcurrent detector (60) whereas it the isolates the triggering relay coil from in connection terminals of the apparatus, and such that in the presence of the detection signal the switching circuit (61) isolates the triggering relay coil of the prolonged overcurrent detector (60) then connects the triggering relay coil to the in connection terminals (22, 23).
