Abstract
A contactor apparatus comprising means for automatically opening power circuits should faults occur and a local control member. This apparatus comprises a plurality of power lines (8) each comprising a power contact (2) adapted to be opened during a short circuit by a striker (28), a coil (13) and a bimetallic strip (14), responding to smaller overloads. The elements responsive to overcurrents act on a cascade of sudden tripping devices (19) (17) (31) which govern the positions of the local control member (18) and act on a control switch (4) placed in series with the electromagnet (1). Such an apparatus is advantageously used in installations where protection of the lines, remote control and local control of the consumer apparatus are desired.
