Abstract
A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and switchable contacts for connecting the fuse to circuitry. A tripping mechanism is provided to disconnect the switchable contacts when predetermined circuit conditions occur.
Claims59
A fusible switch disconnect module comprising:
- a disconnect housing adapted to receive a fuse therein;
- a fuse being removably insertable in the disconnect housing;
- line side and load side terminals communicating with the fuse when the fuse is inserted into the disconnect housing;
- at least one stationary contact and at least one movable contact being selectively positionable along a linear axis with respect to the at least one stationary contact between an open position and a closed position to connect or disconnect an electrical connection through the fuse;
- an actuator causing the at least one movable contact to be positioned between the open position and the closed position;
- a cover coupled to the disconnect housing, the cover concealing the fuse when in a closed position, the cover exposing the fuse when in an open position, and
- an interlock arm positioned between the actuator and the cover, the interlock arm engaging the cover to a locked position when the at least one movable contact is in the closed position, the interlock arm disengaging the cover to an unlocked position when the at least one movable contact is in the open position,
- wherein the locked position prevents the cover moving from the closed position to the open position.

A fusible switch disconnect module comprising:
- a disconnect housing adapted to receive a fuse therein, the fuse being separately provided from the disconnect housing and being removably insertable in the disconnect housing;
- a cover coupled to the disconnect housing and positionable between an open position and a closed position;
- line side and load side terminals connecting to the fuse when the fuse is inserted into the disconnect 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 coupled to 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 adapted to position the sliding bar and first and second movable contacts between the open position and the closed position relative to the first and second stationary switch contacts to connect or disconnect an electrical connection through the fuse;
- and
- a trip mechanism positioned between the rotatably mounted switch actuator and the cover, the trip mechanism engaging each of the rotatably mounted switch actuator and the cover in a locked position when the sliding bar is in the closed position, and the trip mechanism disengaged from each of the cover and the rotatably mounted switch actuator when the sliding bar is in the open position.

- a cover coupled to the disconnect housing, the cover concealing the fuse when in a closed position, the cover exposing the fuse when in an open position;
- an interlock arm positioned between the actuator and the cover, the interlock arm engaging the cover to a locked position when the at least one movable contact is in the closed position, the interlock arm disengaging the cover to an unlocked position when the at least one movable contact is in the open position, wherein the locked position prevents the cover moving from the closed position to the open position;
- at least one bias element urging the at least one movable contact to the open position;
- and
- a tripping mechanism counteracting the at least one bias element under normal operating conditions.
7 more elements
A fusible switch disconnect device comprising:
- means for housing at least one fuse, the at least one fuse being removably insertable into the means for housing;
- means for connecting the at least one fuse to a circuit;
- means for covering the at least one fuse, the means for covering coupled to the means for housing;
- means for switching the means for connecting to connect or disconnect an electrical connection through the at least one fuse, the means for switching located within the means for housing;
- means for actuating the means for switching and selectively positioning the means for switching in an open position and a closed position without removing the at least one fuse from the means for housing;
- and
- means for interlocking positioned between the means for actuating and the means for covering, the means for interlocking engaging the means for covering to a locked position when the means for switching is in the closed position, and the means for interlocking disengaging the means for covering to an unlocked position when the means for switching is in the open position.
