Abstract
A fused disconnect switch device includes a housing defining an interior volume, and a current path. An arc interruption assembly is located in the interior volume and includes a shell, and a conductor in electrical communication with the current path. At least one arc plate is located between the magnets and the conductor. The magnets cooperate to generate a magnetic field facilitating an interruption of a first arc between the conductor and the first side of the arc chamber and a second arc between the conductor and the second side of the arc chamber.
Claims20
A fused disconnect switch device comprising:
- a housing defining a first interior volume;
- a current path defined in the housing for connection to a removable overcurrent protection fuse;
- and
- an arc interruption assembly comprising:
- a shell residing in the first interior volume of the housing and defining a second interior volume and at least one barrier defining opposing arc chambers in the second interior volume;
- a movable conductor selectively positionable in the housing and relative to the shell, the movable conductor switchably connecting or disconnecting the current path in each of the opposing arc chambers;
- arc plates located between the first or second magnet and the movable conductor in the respective opposing arc chambers;
- and
- at least first and second magnets generating a magnetic field across the shell to effect arc deflecting magnetic force that does not depend on polarity of connection to a protected circuit;
- wherein the current path does not involve or include a resettable circuit breaker element.

A fused disconnect switch device comprising:
- a nonconductive housing configured to accept an overcurrent protection fuse;
- a current path defined in the nonconductive housing, the current path comprising a first fuse contact member and a second fuse contact member, the first fuse contact member and the second fuse contact member configured to complete an electrical connection through the overcurrent protection fuse;
- the current path further including a mechanical switch having a movable conductor but not including a resettable circuit breaker element;
- a switch actuator selectively positionable between first and second positions to electrically connect and disconnect the movable conductor in the current path;
- and
- an arc chamber assembly disposed about the movable conductor and separately defined from the housing, the arc chamber assembly comprising at least one pair of magnets, a first plurality of arc plates in a first arc chamber, and a second plurality of arc plates in a second arc chamber, the at least one pair of magnets establishing a magnetic field across the arc chamber assembly to effect arc deflecting magnetic force that does not depend on polarity of connection to a protected circuit;
- wherein the first and second pluralities of arc plates respectively comprise aligned arc plates having a leading edge defining a channel through which respective ends of the movable conductor pass.

A fused disconnect switch device comprising:
- a housing defining an interior volume;
- a current path defined in the housing, the current path including a first fuse contact member, a second fuse contact member, and a mechanical switch having a first stationary switch contact and a second stationary switch contact and a movable conductor member carrying first and second movable switch contacts on opposed ends thereof, and wherein the current path does not include a circuit breaker;
- wherein the first fuse contact member and the second fuse contact member are configured to complete an electrical connection through an overcurrent protection fuse and wherein the first stationary switch contact and the second stationary switch contact each have a stationary turn-back conductive structure;
- and
- an arc chamber assembly comprising:
- at least first and second magnets cooperating to generate a magnetic field therebetween;
- a plurality of arc plates located in the magnetic field;
- and
- a shell in the interior volume of the housing and comprising a first arc chamber, a second arc chamber and a plurality of receptacles in the first arc chamber and in the second arc chamber to individually receive the plurality of arc plates, and the shell integrally formed with receptacles to receive the first and second magnets;
- wherein the at least first and second magnets effect arc deflecting magnetic force in the first and second arc chamber that does not depend on polarity of connection to a protected circuit.
