CIRCUIT BREAKER AT LEAKAGE Russian patent published in 2022 - IPC H01H71/02 

FIELD: electrical engineering.

SUBSTANCE: circuit breaker at a leakage contains an input terminal, a circuit breaker node, a leakage protection node, and an output terminal, located in series along the first direction, wherein the leakage protection node contains a zero sequence transformer, a control circuit located on a printed circuit board, an actuating mechanism, and an output terminal. The zero sequence transformer and the actuating mechanism are located on the first side of the printed circuit board for electronic components in the second direction perpendicular to the first direction.

EFFECT: minimization of energy consumption and increase in a temperature of a leakage protection module, while reducing overall dimensions.
