| 20090108983 | Fuse With Fuse State Indicator - A fuse comprising a fuse state indicator wherein the fuse state indicator may be temperature sensitive. | 04-30-2009 |
| 20090128280 | FUSIBLE SWITCHING DISCONNECT MODULES AND DEVICES - 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. | 05-21-2009 |
| 20090295533 | Fusible Switching Disconnect Modules and Devices - A monitoring module for a fusible switch disconnect device includes an open fuse detecting element and wire leads for completing an electrical connection with a fuse. | 12-03-2009 |
| 20100019878 | Touch Safe Fuse Module with Ampacity Rejection - A fuse and fuse module that facilitate ampacity rejection based on electrical contact location is disclosed. A configuration of electrical contacts in the fuse and a corresponding configuration of fuse slots in the fuse holder permit fuses within an acceptable range of ampacities to be installed in the fuse holder while at the same time preventing fuses within an unacceptable range of ampacities from being installed in the fuse holder. | 01-28-2010 |
| 20100019879 | Touch Safe Fuse Module with Improved Wiring Lugs - A fuse module includes a wiring lug. The wiring lug includes a fuse clip member comprising a first pressure plate and a fuse clip, a lug box comprising a second pressure plate, and a securing member operably coupled to the lug box. The securing member operates between a first position and a second position to move the second pressure plate of the lug box with respect to the first pressure plate of the fuse clip member. The first pressure plate and the second pressure plate have a clamping relationship when the securing member is in the first position and have a non-clamping relationship when the securing member is in the second position. | 01-28-2010 |
| 20100328019 | FUSE WITH FUSE STATE INDICATOR - A fuse includes a fuse state indicator on the exterior surface of the fuse body. The fuse state indicator includes an electrically conductive element electrically connected to and extending between the terminal elements. A temperature sensitive element proximate and in thermal contact with the electrically conductive element includes material capable of changing color when heated to a predetermined transition temperature to form a mark on the temperature sensitive element. The fuse state indicator forms a first mark on the temperature sensitive element when heat from the electrically conductive element transfers to the temperature sensitive element in response to a first overcurrent condition, and forms a second mark, distinct from the first mark, on the temperature sensitive element when heat from the electrically conductive element transfers to the temperature sensitive element in response to a second overcurrent condition distinct from the first overcurrent condition. | 12-30-2010 |
| 20110057760 | FUSE STATE INDICATOR SYSTEMS - 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. | 03-10-2011 |
