Abstract

1339740 Heavy current switches MAGRINI FABBRICHE RIUNITE MAGRINI SCARPA E MAGNANA MSM SpA 18 Dec 1970 [18 Dec 1969] 60384/70 Heading H1N A circuit breaker has two fixed contacts 1, and a movable frame 8, 9, 10 supporting bridging contacts 6, 7, contacts 6 being arcing contacts. The movable contacts have projections 12 which engage in slots in the frame sides 9, and are resiliently supported by springs 13. A pivoted control lever 14 has two tie rods pivoted to it at one of their ends, their other ends being connected to respective axles 18. Connecting rods 21 are connected between axles 18 and further axles connected to the frame side 9, carrying the contacts 6, 7. Rotation of the lever 14 causes the tie rods to move the axles 18 thus raising and lowering the frame to close or open the contacts. Arcing contacts 6 disengage after and engage before, the contacts 7. The circuit breaker is connected across an electrolytic cell so as to short it out when in the closed position.
