Abstract
A high current fusible disconnect switch device includes a switch housing configured to receive a pluggable touch-safe fuse module, and a dual slide bar actuator assembly for opening and closing switch contacts. The dual slide bar elements are each coupled to bias elements that store and release energy to affect switch opening and closing operations. The switch opening and closing operation is multi-staged wherein the only the first slider element is movable in the first stage, and both the first and second slider elements are movable in the second stage.
Claims20
A fusible disconnect switch device comprising:
- a switch housing configured to accept a removable fuse;
- a line side terminal and a load side terminal in the switch housing;
- a switch actuator selectively positionable between an opened position and a closed position;
- and
- a slider assembly linked to the switch actuator and responsive to the position of the switch actuator to effect a switch closing operation or a switch opening operation via selective positioning of at least one switch contact to make or break an electrical connection to the load side terminal;
- and
- a first pair of bias elements each having a first end and a second end, the first end of each of the first pair of bias elements directly attached to the housing and the second end of each of the first pair of bias elements directly acting upon a respective one of opposing sides of the slider assembly, wherein each the first pair of bias elements are simultaneously compressed by the selective positioning of the slider assembly or simultaneously decompressed by the selective positioning of the slider assembly to cooperatively store and release energy to effect a switch closing operation or a switch opening operation.

- a switch actuator selectively positionable between an opened position and a closed position;
- and
- a slider assembly linked to the switch actuator and responsive to the position of the switch actuator to effect a switch closing operation or a switch opening operation via selective positioning of at least one switch contact to make or break an electrical connection to the load side terminal;
- a first pair of bias elements each having a first end and a second end, the first end attached to the housing and the second end acting upon opposing sides of the slider assembly to store and release energy to effect at least one of a switch closing operation or a switch opening operation;
- and
- a second pair of bias elements each having a first end and a second end, the first end attached to the housing and the second end acting upon opposing sides of the slider assembly to store and release energy to effect at least one of the switch closing operation or the switch opening operation;
- wherein the slider assembly comprises a first slider element and a second slider element each slidably movable with respect to the switch housing and slidably movable with respect to one another;
- wherein the first pair of bias elements connects to the first slider element and wherein the second pair of bias elements connects to the second slider element;
- and
- wherein in a first stage of the switch opening operation the first slider element is driven to move by the switch actuator while the second slider element remains stationary.
