Abstract: Described herein is a VI assembly that includes a VI having a stationary contact on a stationary contact potential, a moveable contact on a moveable contact potential, and a vapor shield. The stationary and moveable contacts define a contacting area. The moveable contact is moveable relative to the stationary contact along an axis of the VI. The VI assembly further includes at least one field coupler. The stationary contact and the vapor shield have a predetermined stationary contact-vapor shield capacitance with respect to each other. The moveable contact and the vapor shield have a predetermined moveable contact-vapor shield capacitance with respect to each other. The field coupler is configured such that it adds a field coupler capacitance to at least one of the stationary contact-vapor shield capacitance and the moveable contact-vapor shield capacitance to make the stationary contact-vapor shield capacitance and the moveable contact-vapor shield capacitance substantially equal.

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.
