Abstract
A high-voltage circuit breaker comprises a first main contact and a second main contact extending along a central longitudinal axis and being at least partially enclosed by an insulator, wherein the insulator has an inner surface facing the central longitudinal axis and being arranged at a first distance from the central longitudinal axis, and further comprises at least one particle trap for trapping particles generated during operation of the circuit breaker, wherein the particle trap has an inner surface facing the central longitudinal axis and being arranged at a second distance from the central longitudinal axis, the second distance being larger than the first distance.
