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.
Claims36
A fusible disconnect switch device comprising:
- a switch housing configured to accept a pluggable fuse module;
- 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 a position of the switch actuator to effect a switch closing operation or a 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 along a linear axis, a first bias element acting on the first slider element and a second bias element acting on the second slider element;
- wherein the first slider element is independently movable relative to the second slider element;
- wherein the second slider element carries at least one switch contact to make or break an electrical connection to one of the line side terminal and the load side terminal;
- wherein the second bias element is mechanically isolated from the switch actuator in a first stage of the switch opening operation;
- and
- wherein the first and second bias elements each provide an opening force in a second stage of the switch opening operation.
