Low current consumption timer type circuit breaker circuit consists of an a.c. source with three switching units based on electrodes

摘要

The low-current consumption timer-type circuit breaker circuit comprises an a.c. soruce (AC), a timing switch (SW), and electrodes (G1,G2,D1,D2,S1,S2), with the current flowing in both directions through the first (11) of two conduction lines. A third switching unit (T3) with electrodes (G3,D3,S3) is also provided in the two-pole circuit.
