Abstract
Fusible switch disconnect modules including a housing means adapted to receive at least one fuse therein, switchable contacts for connecting the fuse to circuitry and having at least one stationary contact and at least one movable contact selectively positionable between an open position and a closed position to connect or disconnect an electrical connection through the fuse, and a means for biasing or bias element assisting movement of the movable contact to the open or disconnected position.
Claims27
A fusible switch disconnect module comprising:
- a disconnect housing adapted to directly receive at least one fuse therein without use of a fuse carrier, the fuse being removably insertable in the housing;
- line side and load side terminals communicating with the at least one fuse when the fuse is inserted into the housing;
- and
- switchable contacts provided between one of the line side terminal and load side terminal of the disconnect housing and the fuse, the switchable contacts comprising at least one stationary contact and at least one movable contact being selectively positionable along a linear axis with respect to the stationary contact between an open position and a closed position to connect or disconnect an electrical connection through the fuse;
- and
- a bias element assisting movement of the movable contact to the open position.
A fusible switch disconnect device comprising:
- means for housing at least one fuse, the fuse being removably insertable into the means for housing without utilizing a fuse carrier;
- means for connecting the fuse to a circuit;
- means for switching the means for connecting to connect or disconnect an electrical connection through the fuse, the means for switching located within the means for housing;
- and
- means for actuating the means for switching and selectively positioning the means for switching in opened and closed positions without removing the fuse from the means for housing;
- and
- means for biasing the means for switching to the disconnected position.
A single pole fusible switch disconnect device comprising:
- a disconnect housing adapted to directly receive a fuse therein, the fuse being separately provided from the housing and being removably insertable in the housing without the use of a fuse carrier;
- line side and load side terminals connecting to the fuse when the fuse is inserted into the housing, at least one of the line and load-side terminals comprising a first stationary switch contact provided between the respective line side terminal and load side terminal and the fuse;
- a fuse terminal adapted to engage a conductive element of the fuse when inserted into the disconnect housing, the fuse terminal comprising a second stationary switch contact;
- a sliding bar within the disconnect housing, the sliding bar provided with first and second movable contacts corresponding to the first and second stationary switch contacts;
- a rotatably mounted switch actuator to position the sliding bar and first and second movable contacts between an open position and a closed position relative to the first and second stationary switch contacts to connect or disconnect an electrical connection through the fuse;
- wherein when the switch actuator is rotated to position the sliding bar and the first and second movable contacts to the open position, the sliding bar pulls the first and second movable contacts away from the first and second stationary switch contacts.
