An arc flash mitigation system includes a main circuit protector such as a high amperage overcurrent protection fuse, and an arc flash mitigation network connected in parallel to the main circuit protector. The arc flash mitigation network includes at least one semiconductor switch operable to provide a shunt current path to a low amperage arc mitigation fuse for a faster response time to certain circuit conditions than the main circuit protector otherwise provides. The semiconductor switch may be a silicon controller rectifier operatively responsive to a voltage drop across the main circuit protector in use.

An embodiment of an arc flash reduction maintenance system includes a pyrotechnic disconnect module and an overcurrent protection device connected to the pyrotechnic disconnect module. A control line is connected to the at least one pyrotechnic disconnect module and in parallel with one of the pyrotechnic disconnect module and the overcurrent protection device. The control line provides a self-generating control signal to cause the pyrotechnic disconnect module to electrically isolate the overcurrent protection device. A switch is located in the control line to selectively enable or disable at least one arc flash reduction maintenance system mode in the control line.

A removal tool accessory for replacing rectangular fuse modules of a fusible switching disconnect device. The removal tool accessory is a single piece part configured to snap-fit with the rectangular fuse module via opposing lateral sides thereof. The accessory includes an opening dimensioned to receive a person's index finger, middle finger, ring finger, and baby finger. A handlebar is provided for optimal mechanical leverage to pull the rectangular fuse module from the fusible switching disconnect device even when access to the rectangular fuse module is restricted.

Circuit protector monitoring assembly kit and method

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.

System and method for circuit protector monitoring and management

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.
