| Number | Title | Issue Date |
| 7289309 | Isolation apparatus The apparatus is intended for disconnection of a live electrical conductor and has an enclosure (3) and two power connections (1, 2) which are passed out of the enclosure (3). A conductor section (7) which connects the two power connectio... | 10/30/2007 |
| 7138899 | Fuse element with a temporary quasi-hermetic seal of its interior A fuse element includes a fusible conductor which extends within a gas filled cavity in a cylindrical tube. The fuse element includes a cylindrical tube comprising, an electrical insulator between two end faces of the tube, two end caps of an electrically conductive... | 11/21/2006 |
| 7119652 | Method of avoiding arc prolongation on current interruption, particulary a fuse A fuse assembly is disclosed. The fuse assembly includes an electrically insulating hollow casing of a substantially rectangular parallelepiped shape in outline, a fuse element provided within the casing and supported by the casing, the casing having first and secon... | 10/10/2006 |
| 6720858 | Fuse In a fuse chamber (8) there is arranged as a quenching gas source a burn-off element (11), which concentrically surrounds an arc chamber (10) and is separated from it by a fuse element (9), which consists of metal foil, preferably silver ... | 04/13/2004 |
| 5179436 | Electric fuse The invention relates to an electric fuse with a fuse element located in a housing which encases a fuse element chamber. The fuse element melts and thus cuts out the fuse under an overcharge, whereby the temperature and pressure in the interior of the cas... | 01/12/1993 |
| 4904977 | Supersonic expulsion fuse This invention provides a supersonic expulsion fuse for interrupting fault currents in high voltage alternating current networks. It creates an arc interruption region with a long length of supersonic turbulent flow and little or no subsonic plasma. This ... | 02/27/1990 |
| 4514716 | Fuse The fuse comprises an elongated support formed at least partially from ferrite, magnetized in the direction of its thickness and on which is disposed, between two terminals, a metal wire (9) capable of being destroyed by melting. The fuse comprises for ex... | 04/30/1985 |
| 4307368 | Electric fuse having gas evolving means for limiting burnback The process of circuit interruption by an electric fuse can be initiated either by a protracted overload, or by a major fault current of large proportions. This invention is concerned with the latter kind of fault currents. A substantially U-shaped gas-ev... | 12/22/1981 |
| 4099155 | Gas actuated high voltage bushing An electrical connector system including a cable terminator having a conductive probe and a bushing having a bore contact mounted for reciprocal movement in an electrically conductive tubular member and a fusible member positioned between the bore contact... | 07/04/1978 |
| 4063297 | Electric arc interrupter and circuit breaker An arc interrupter for heavy surge currents in power systems is provided in hich a self-biasing, spring helix conductor is fixed between two frangible and/or fusible elements which are in turn integrally fastened to the edges of respective eddy-current rin... | 12/13/1977 |
| 4032879 | Circuit-protecting fuse having arc-extinguishing means A circuit-protecting fuse comprises an insulating housing having electrically conductive connectors on opposite ends thereof to connect the fuse in an electrical circuit and at least one fusible link in the housing connected in electrically conductive rel... | 06/28/1977 |
| 3965452 | Exhaust control device for circuit interrupting devices An exhaust control device to absorb the energy of exhaust gases released during operation of a circuit interrupting device such as a power fuse or an expulsion fuse is disclosed. The exhaust control device includes a housing mounted to the circuit interru... | 06/22/1976 |
