摘要： An improved fuse including a fuse body formed of an electrically insulative material. The fuse body defines a cavity which extends from a first end of the fuse body to a second end of the fuse body. A fusible element is disposed within the cavity and extends from a first end face of the first end of the fuse body to a second end face of the second end of the fuse body. Insulated plugs are disposed within the cavity at the first and second ends of the fuse body wherein the plugs adhere to an interior surface of the fuse body and form seals that close the internal cavity. The fuse may further include end terminations that are applied to the ends of the fuse body in electrical contact with the fusible element.

摘要： A circuit protection assembly can include a conductive assembly post that supports a first conductive element, a non-conductive isolator, a second conductive element, a fuse, and a fastener. The first and second conductive elements can be positioned in close proximity to one another below the fuse. A first portion of the isolator can separate the first and second conductive elements. A second portion of the isolator can separate the conductive assembly post from the second conductive element. The first conductive element can be coupled to a power source and the second conductive element can be coupled to a downstream circuit. The fuse can protect the downstream circuit during specified overvoltage and/or overcurrent conditions and can be quickly and efficiently installed and replaced without the need to remove or reattach the conductive elements or any other cabling or wires.

摘要： A protective device including a substrate, a conductive section and a bridge element is provided. The conductive section is supported by the substrate, wherein the conductive section comprises a metal element electrically connected between first and second electrodes. The metal element serves as a sacrificial structure having a melting point lower than that of the first and second electrodes. The bridge element spans across the metal element in a direction across direction of current flow in the metal element, wherein the bridge element facilitates breaking of the metal element upon melting.

摘要： A fuse link includes a conductive terminal component having a cylindrical insertion region with a knurled region formed therein and a fusible element electrically coupled thereto. A tubular sheath is configured to form a press-fit connection with the knurled region such that the tubular sheath substantially encloses the fusible element. The inner radius, the wall thickness, and the length of the tubular sheath are together configured to remain substantially intact when the fusible link experiences a first overload event within a first range of fault current values and burst when the fusible link experiences an overload event within a second range of fault current values that is greater than the first range.
