Abstract (en)

An energy absorption device (1) for a circuit breaker, in particular a solid-state or a hybrid circuit breaker, includes an energy absorber (20) arranged within an enclosure (10) and a two-phase cooling arrangement. The two-phase cooling arrangement has one or more fluid distribution units (110) configured to direct a cooling fluid in a liquid state toward the energy absorber (20), the energy absorber (20) being cooled due to evaporation of the cooling fluid.A circuit breaker, in particular solid-state or hybrid circuit breaker, includes one or more energy absorption devices (2, 3, 4).A method for two-phase cooling of an energy absorber (20) of a circuit breaker, in particular a solid-state or hybrid circuit breaker, includes: after a switching operation of the circuit breaker, directing a cooling fluid in a liquid state toward the energy absorber (20). Thereby, the energy absorber (20) is cooled due to evaporation of the cooling fluid.
