Method for release of low-voltage circuit-breakers involves energy for activating actuation magnet and interval timer alone obtain actuating signal of electronic over current release

摘要

The method involves energy such that the energy for activating the actuation magnet (A1,A2,A3) and the interval timer alone obtains the actuating signal of the electronic over current release. The energy of the initiation signal in a condenser (C) is temporally retentive. The energy turns off the process of the low-voltage circuit breaker through a controlled network. An independent claim is also included for the circuit arrangement.
