Apparatus and methods for limiting electrical current in circuit breaker applications

摘要

Apparatus and methods for limiting transient current in an electrical power system in response to an over-current condition where a current-limiting electronic circuit breaker senses electrical current flowing in a circuit and isolates the electrical power source when the current is greater than a first preset value. During the time delay from the time that the electrical current increases above a first preset value and until circuit breaker opens, where the electrical current increases above a second preset value, greater than the first, the electrical current is limited to a maximum value.
