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 solid state switch for connecting and disconnecting an electrical device has at least one FET-type device and at least one thyristor-type device coupled in parallel to the at least one FET-type device. A gate driver is operative to send gate drive signals to the at least one FET-type device and to the at least one thyristor-type device for providing current to the electrical device. The gate driver is constructed to control a split of the current as between the at least one FET-type device and the at least one thyristor-type device.

Abstract: A switching device for low-voltage or medium-voltage applications including: one or more electric poles; for each electric pole, at least a fixed contact and at least a movable contact, each movable contact being reversibly movable between a coupled position, at which the movable contact is coupled with a corresponding fixed contact, and an uncoupled position, at which the movable contact is separated from the fixed contact, wherein a separation gap is present between the movable contact and the fixed contact, when the movable contact is in the uncoupled position. The switching device includes, for each electric pole, at least an arc-diverting element made of electrically insulating material.
