Estimating the term…
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.
A circuit breaker comprising at least one ejection device comprising an arc-extinction medium and/or exhaust-cooling medium for improving circuit breaker operation, and in particular for improving extinction of an arc formed during a breaker operation, wherein the arc-extinction medium and/or exhaust-cooling medium comprises an organofluorine compound having a boiling point Tb at 1 bar higher than −60° C. and being selected from the group consisting of:
A method for improved circuit breaker operation in a circuit breaker, in particular for improved extinguishing of an arc and/or for improved cooling of exhaust gases formed in a circuit breaker, wherein a liquid arc-extinction medium and/or liquid exhaust-cooling medium comprises an organofluorine compound having a boiling point Tb at 1 bar higher than −60° C. and being selected from the group consisting of:
