Abstract

1530890 Arc-rupturing in switches SEIMENS AG 23 Sept 1977 [27 Sept 1976] 39838/77 Heading H1N Arcing between contacts 1, 7 of a circuitbreaker is interrupted in a quenching chamber with at least one quenching plate 2 extending transversely (preferably perpendicularly) of the direction 3 of relative contact movement and having a thickness of 2 to 5 mm. and a thickness 12 to length 15 ratio in the range of 1 : 4 to 1 : 2 as well as being spaced from the point of contact 9 by a distance 14 which is between 3 and 8 times the thickness 12. Passages 20, 21 allow for air flow on arcing.
