Abstract (en)
[origin: EP1775744A2] The three pole power switch (1) has a switch lock (14), where each pole (5-7) has its own rapid short circuit trip (19-22) to act on a trip shaft. The lock has four adjacent poles, where the two inner poles (6',6") are switched in parallel as a common inner pole. The inner poles and an outer pole (5), on a short circuit, act against the pressure of an elastic return unit (24) at a part shaft (23) of the trip shaft. The trip, on a short circuit at the other outer pole (7), acts against an elastic return unit on a second plastics part shaft (28) to lock the part shafts together.
