Abstract: An arc chamber for a DC circuit breaker includes an entry side adapted to receive an electric arc, which was generated outside of the arc chamber and which propagates in a forward direction, a plurality of stacked splitter plates, and at least one inhibitor barrier. The at least one inhibitor barrier is arranged on the entry side to inhibit a reverse propagation of the electric arc out of the arc chamber in a reverse direction. DC circuit breaker comprising an arc chamber. Use of an arc chamber with a circuit breaker in a DC electrical system.

Abstract: A DC circuit breaker including a pair of arcing contact members for holding an arc, an interaction element, adapted for interacting with the arc in dependence of whether the arc is in a first or second state such that the arc voltage drop in the first state is lower than the drop in the second state, a resonance branch coupled in parallel to the contact members thereby forming a resonance circuit adapted for letting a resonance branch current Ir oscillate thereby inducing oscillations of an arc current Ia, wherein the resonance branch includes a coupling element for coupling the resonance branch with the arc, such that the arc is brought to the first state when the current Ir in the resonance branch has a first direction, and that the arc is brought to the second state when the current Ir in the resonance branch has a second direction.
