Abstract

The invention provides an electronic circuit for carrying out at least three measurements, comprising at least one controller (10), at least three current sensors (54), at least three voltage sensors (55), and at least three relays (211). The smart circuit breaker (K) is used for the protection of photovoltaic systems, characterized in that it comprises at least one web connection unit (12), the circuit breaker control card (20), which triggers said circuit breaker (21), which provides detection of island mode, voltage collapse, and voltage jump.
