COMBINED PROTECTIVE CUTOUT DEVICE Russian patent published in 2012 - IPC H02H3/00 

Abstract RU 2441305 C1

FIELD: electricity.

SUBSTANCE: combined protective cutout device comprises a leakage current sensor (1), a peak rectifier-amplifier (2), an inertial RC-circuit with time-setting resistor and capacitor (3), a threshold element (4), an actuator element (5), a supply source (6), a stabilitron (7), a comparator (8), an element of logical OR (9), the second time-setting resistor (10), a controller divider (11), a resistor (12), the first (13) and second (14) thyristors.

EFFECT: expansion of functional capabilities, due to provision of half-wave leakage of current via a load after opening of a circuit with actuator contacts.
