FIELD: electricity.
SUBSTANCE: combined protective cutout device comprises a leakage current sensor (1), a peak rectifier-amplifier (2), an inertion RC-circuit with a time-setting resistor and a capacitor (3), a threshold element (4), an actuator (5), a source of power supply (6), a stabilitron (7), a comparator (8), an element of logical OR (9), a second time-setting resistor (10), a controlled 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 through a load after opening of a circuit with contacts of an actuator.
