First Claim
Patent Images
1. An electronic circuit breaker with an input for connection to a power-supply network and an output for connection to a load, comprising:
- between said input and said output at least one switch and at least a limitation block which controls said switch to cause partial inhibition thereof in the event of over-current; and
a microprocessor connected to said limitation block to cut off power supply to the load after a time delay following partial inhibition of said switch.

Abstract
The electronic circuit breaker comprises an input for connection to a power-supply network and an output for connection to a load. Set between the input and the output are a switch and a limitation block which controls the switch to cause at least partial inhibition thereof in the event of over-current. The circuit breaker further includes a microprocessor connected to the limitation block to inhibit power supply to the load.

25. A method for controlling a circuit breaker, including the steps of:
-
arranging at least an electronically controllable switch between an input and an output of said circuit breaker; providing a microprocessor controlling said switch; powering a load through said circuit breaker; detecting a current flowing through said circuit breaker; when the current exceeds a current threshold, partially inhibiting said switch; and upon a given time delay following partial inhibition of said switch, if said current still exceeds said threshold, cutting off power supply through said circuit breaker. - View Dependent Claims (26, 27, 28, 29, 30, 31)
