Protective circuit breaker with time-delay release has energy reservoir for release unit fed by supply unit connected to supply side to guarantee continue loading independent of whether switch contacts are open or closed

摘要

Energy reservoir (E) for the release unit (A) is fed by a supply unit (SV) connected to the supply side, guaranteeing that the energy reservoir is always loaded independently of whether the switch contacts (S1,S2) of the circuit breaker are open or closed. Preferably other electronic components are supplied by power by the supply unit connected to the supply side.
