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: Fuse state indicators for use with disconnect devices having a fuse are provided. Fuse state indicators include a housing having circuitry, a detecting means for detecting an open circuit condition, conductors adapted for electrical connection to a disconnect device so as to complete a circuit connecting the detecting means with a fuse of the disconnect device, and a signal transmitting means The detecting means is configured to transmit a signal to the signal transmitting means for determining an operational state of the fuse. The signal transmitting means, in turn, is configured to transmit a signal to a remote device the state of the fuse.

Abstract: A fusible disconnect device having auxiliary connections to line-side and load-side terminals and color coding features to indicate an amperage rating of a fuse.

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.

Abstract: A rotary switch containing fuse capabilities. An electrical contact disc is rotatively mounted in a housing. A handle assembly is mounted to the electrical contact disc and rotates therewith, and is replaceably mounted in the housing so as to allow the handle assembly to be removed from the housing and prevent inadvertent operation of the rotary switch. A pin extends in the handle assembly and a fuse retainer and engages a horse shoe clip, and in doing so, axially movably attaches the fuse retainer to a fuse-holding disc. The pin then extends in a bushing. A pair of blind slots in the pin engage a hair pin clip, and in so doing, the handle assembly can rotate relative to, but cannot be removed from, the housing, unless the pin is rotated 90 degrees, which would orientate the pair of through slots out of engagement with the hair pin clip.

Abstract: A switch breaker includes having a body; a press button having a link; a metal sheet having an electrical contact; a elastic member; a first terminal having a point contact; a second terminal; and a cover, characterized in that a protrudent part is formed on a suitable place on the metal sheet. After one end of the press button is pressed, the insulator does not push the protrudent part of the metal sheet so that the electrical contact contacts the point contact and the switch breaker is at a conducting state. When the current load is too large and the metal sheet is too hot and bent, or when the other end of the press button is pressed and the insulator pushes the protrudent part, the electrical contact is separated from the point contact and the switch breaker is at a nonconducting state. The design of pushing the protrudent part backward by the insulator to move the left end of the metal sheet backward can prevent the occurrence of arc between the electrical contact and the point contact.

Abstract: A molded case circuit breaker and current suppressing unit protects an electric motor without tripping during motor current reversal. Upon the occurrence of a short circuit within the protected circuit, the current suppressing feature rapidly suppresses the let-through current until the circuit breaker responds to isolate the protected equipment. Power is restored to the protected equipment without the need to replace any of the current suppressing unit components.

Abstract: In an office machine, in particular in a matrix printer which is provided with a power grid component (3) for the power supply of the electrical or, respectively, the electronic circuits and which includes a safety fuse on the power grid input side, there is disclosed for purposes of more clarity of the construction, for an easier operability and for protection against false connection, that a multiple safety fuse socket (6) for at least two melting safety fuse bodies (9, 10) is coordinated to a voltage selection switch (7). The multiple safety fuse socket (6) can be placed in different relative geometric positions with respect to the voltage selection switch (7) into a fuse socket (8). A selected voltage is coordinated at the voltage selection switch (7) in each position of the multiple safety fuse socket (6).

Abstract: The invention relates to a power entry module for supplying power from an outside source to equipment with which the power entry module is in association. The module is made up of a one piece housing divided into at least two compartments with a first compartment having means housed therein for connection to an outside power source. A second compartment includes respective fuse clips for use with different size fuses for routing power from the outside power supply through the fuses and into the equipment requiring the power. A voltage card enables selection of the outside power supply within predetermined ranges and converts the incoming voltage to that required by the equipment depending upon the position of the card. A cover is hinged to the housing and when in closed position with an outside power supply plugged into the power entry module, has means for preventing opening of the cover to prevent access to the fuse compartment to avoid the danger of shock.

Abstract: An A.C. power entry module for supplying A.C. power to equipment which provides A.C. fusing, power on-off switching, RFI filtering and selection of voltage. The module can be utilized for both U.S. and European style fusing and a number of different voltage options are available which can be selected by merely changing the position of a circuit board. The contacts for engaging the fuses are mounted such that an operator cannot come in contact with them and the European or U.S. fuses can be easily selected by inverting a fuse holder board.

Abstract: A combined cartridge fuse holder and switch incorporates the cartridge fuse as part of the switching mechanism. One end of the cartridge fuse is pivoted about a fulcrum contact coupled to a first terminal. A switch assembly swings the other end of the cartridge fuse transversely relative to the fuse axis to make and break contact with a contact on a second terminal.

Abstract: Disclosed is an interrupter switch mechanism for interrupting current flow in a high voltage electrical circuit. A tubular switch blade is mounted for linear movement to engage and disengage a stationary contact. A spring is positioned within the hollow interior of the tubular switch blade so that it can be biased in either direction by sliding plugs also positioned within the tubular switch blade. The sliding plugs include pins which engage a slot in a plate member so that movement of the plate member in either direction causes one or the other of the plugs to move to bias the spring in that direction. The plate member has gear teeth formed thereon for engaging mating teeth on a tool engaging disk. The tool engaging disk has an opening therein for engaging the end of an insulated tool which may be rotated to operate the mechanism. The plate member also has cam surfaces which engage first and second cam follower members to cause these cam follower members to pivot.
