An improved breaker for high current or voltage applications, for instance industrial and/or railways applications, is provided wherein a high current must be switched on/off or interrupted with high efficiency and extremely fast intervention times. The breaker may include a base portion including an activating mechanism including a holding mechanism and a release mechanism, an intermediate switching or breaking contact portion, including fixed contacts and movable contacts, and a top arc chute extinguishing portion covering the intermediate switching or breaking contact portion.

Breaker for high D.C. current or voltage applications, for instance industrial and/or railways applications

An improved contactor device for high current switching applications, in particular industrial or railways applications, is provided, wherein a high DC current must be switched on and off, the contactor device includes a switch base portion including an electric switching mechanism of a high voltage portion and an arc extinguishing portion covering the switching mechanism. The contactor device includes a couple of moving contacts driven towards and away from each other with respect to a mutual contact and abutting position, those moving contacts being mounted at the respective contact ends of a toggle mechanism activated by a low voltage driving portion incorporated in the switch base portion and active on the toggle mechanism.

Contactor device for high current switching applications

An improved high speed breaker for industrial or railways applications wherein a high D.C. current must be interrupted with high efficiency and extremely fast intervention times. The breaker includes, in a casing, a base portion supporting an activating a switching mechanism including a holding mechanism and a release mechanism, an intermediate switching or breaking contacts portion, including fixed contacts and movable contacts, and a top arc chute extinguishing portion covering the switching or breaking contact portion, wherein intermediate delimiting portions are provided on both sides of the casing to delimit laterally the intermediate switching or breaking contact portion and to provide lateral guides for the arc chute extinguishing portion, wherein the arc chute extinguishing portion is slidably mounted in the casing, and wherein at least a lever mechanism is extended transversally between the opposite intermediate delimiting portions for moving or raising the arc chute extinguishing portion for inspection.

High speed circuit breaker for industrial and railways applications

A mono or bidirectional contactor device for applications involving switching of the power supply for high current and/or voltage electrical loads, of the type comprising a containing and protective casing made of synthetic plastic insulating material with a bottom wall from which there extends an actuator portion, comprising a coil and auxiliary contacts, an intermediate portion for housing fixed and movable contact poles, and an upper arc chute portion for dissipating the electric arc. Advantageously the casing is chosen so as to have a flat parallelepiped form with the bottom wall extending at 90&#xb0; with respect to a side wall of the casing on the shorter side and a support plate for the contactor is connected to the outer surface of the base wall or of said side wall so as to support the casing substantially with a vertical extension from the horizontal plane or projecting from the vertical plane.
