Abstract:
A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to move the switchable contact to an open position in response to a predetermined electrical condition.
Abstract:
A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to displace the switchable contact, as well as multiple other components in the device, in response to a predetermined electrical condition.

Abstract:
A fusible switch disconnect device includes a housing adapted to receive a fuse therein, and switchable contacts for connecting the fuse to circuitry. Line side and load side terminals in the housing electrically connect to the fuse when the fuse is received and engaged with the housing. A current detecting element is configured to detect current flow through the switchable contacts when the switchable contacts are in a closed position. A disconnect mechanism is operable in a first mode and a second mode to displace the switchable contacts. The first mode is manually operated and the second mode is responsive to an actual electrical circuit condition when the line side terminal is connected to energized line circuitry.
Abstract:
A compact fusible disconnect switch device having a reduced switch housing size and increased power density is configured to be face mounted to a panel. A fuse cover assembly allows installation and removal of a fuse without having to open the panel. Line-side and load-side terminals are provided on a common side of the housing. In-line mechanical ganging and simultaneous application is provided for combinations of the compact fusible disconnect switch devices.
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.
