The present invention relates to a residual current circuit breaker, RCCB, (100) for an electrical circuit (300). The RCCB comprises a first switching device (106) and a second switching device (140) coupled in series with each other between the power supply (302) and the load (304). The first switching device (106) is configured to switch into an OFF mode, in which no current is fed to the load (304), upon detecting that a value of a current i fed to the load (304) is larger than a switching current is of the first switching device (106). The second switching device (140) is configured to switch into an ON mode, in which the load (304) is short cut, upon detecting a leakage of the current i fed to the load (304). Thereby, a novel RCCB architecture is provided. When a current leakage is detected a short cut is introduced which means that the voltage will be zero over the load and no person will be harmed by the current in the circuit. Flowever, when the load is short cut there will be a current rush in the circuit which will trigger the first switching device to break the circuit and no current will thereafter flow in the circuit. The invention also relates to a circuit comprising such a residual current circuit breaker and a corresponding method.

Conventional GFCI-type technology typically relies solely on onsite control—for example, pushing a reset button physically located at the impacted circuit to clear a trip and resume operation. For simpler/lower voltage systems—such as outlets in a residence—this is not particularly labor-intensive or confusing. However, for large, complex, and/or high voltage systems—such as sports lighting systems with multiple circuits dozens of feet apart in locked enclosures—trying to perform the same task of pushing a reset button and clearing a trip is much more labor-intensive, and confusing not only in locating the impacted circuit, but in determining what happens next if pushing the reset button does not resume operation. Presented herein are remote control options for GFCIs which could be used in addition to, and not instead of, conventional GFCI-type functionality—or could provide remote-only reset function where a system has no onsite reset button.

The disclosure provides an electronic device including a driver circuit and a driving method thereof. The driver circuit includes an electronic unit, a driver unit, and a detection and protection circuit. The driver unit is electrically connected to the electronic unit. The detection and protection circuit is electrically connected to the electronic unit through a first node, and is electrically connected to a gate terminal of the driver unit through a second node.
