Abstract (en)
[origin: DE19806944C1] The LV protection switch has an insulating housing containing U-shaped terminal rails with fixed contacts and cooperating contact bridges supported by a switch traverse (3) of a duroplastics material. The contacts move together at a rate of at least 3 m/s with a contact stroke of at least 8mm, the switch base plate (12) made of an elastic thermoplastics for pressing arc extinction inserts (11) towards the fixed contact carriers (7), the arc chamber wall having a labyrinth exit path for the arc plasma.
