Abstract:
A circuit protector signal transmission system, kit and method involves at least one circuit protector defining an interruptible current path therethrough upon an occurrence of specified operating conditions in a circuit, a status element associated with the circuit protector and adapted to monitor an operating state of the current path, an electronic gateway device in communication with the status element and adapted to receive a data signal from the status element corresponding to the operating condition of the current path. The data signal includes location information and identification information for circuit protectors as they operate to interrupt the current paths in an electrical system.
Abstract:
A system and method for circuit protector monitoring and management includes at least one circuit protector defining an interruptible current path therethrough upon an occurrence of specified operating condition in a circuit; a status element associated with the circuit protector and adapted to monitor an operating state of the current path; and an electronic management system in communication with the status element, wherein the management system is adapted to automatically alert and summon responsible personnel when the circuit protector has operated to open the circuit path, and identify the location of the operated circuit protector.
Abstract:
A fuse state indicator includes a fuse casing having a transparent lens, a combustible substance disposed adjacent the lens, and a base layer disposed adjacent the combustible substance and having a contrasting color relative to the combustible substance. A secondary fuse indicating circuit is electrically connected to a main fuse circuit in parallel with a main fuse link, and includes a secondary fuse wire link which is disposed adjacent the combustible substance. Heat created upon vaporization of the secondary fuse link ignites the combustible substance and reveals the base layer through the lens after combustion, thereby indicating a state of the fuse as operable or inoperable by the color visible through the lens. Combustion may be assisted with an energetic chemical compound applied to secondary fuse wire link and combustible substance.
