摘要: A circuit breaker including an ejection device with a compartment, in which an arc-extinction medium for improving circuit breaker operation is contained, and having an ejection orifice through which the arc-extinction medium is to be ejected, wherein the ejection orifice opens out into an injection zone of the circuit breaker in which the pressure is lower than in an arcing zone when an arc is present, and wherein the arc-extinction medium and/or exhaust-cooling medium is at least partially present in liquid form, when it is contained in the ejection device.

摘要: A circuit breaker including an ejection device including an arc-extinction medium for improved extinction of an arc formed during a breaker operation and an exhaust-cooling medium for improved cooling of exhaust gases in the circuit breaker. Thereby, the arc-extinction liquid includes an organofluorine compound having a boiling point Tb at 1 bar higher than −60° C. and being selected from the group of: a fluoroether; a fluoroamine; a fluoroketone; and mixtures thereof.

摘要: An electrical switching device for medium or high voltage circuits having at least a nominal contact arrangement, wherein the nominal contact arrangement includes at least a first nominal contact including a plurality of contact fingers forming a finger cage concentric with respect to a longitudinal axis, wherein the contact fingers are separated from one another by empty slots extending up to a free end of the contact fingers. The empty slots include first and second empty slots, wherein the second empty slots are shorter than the first empty slots, and wherein the contact fingers are grouped in groups, with the contact fingers of each group being separated by second empty slots and the contact fingers of adjacent groups being separated by first empty slots.
