| 20090066471 | Fuse arrangement - The invention relates to a fuse system for a switchgear assembly, especially for a medium voltage switchgear assembly. The fuse system comprises a plurality of fuses which correspond to the number of phases, every fuse having a tripping bar that projects from the face of the fuse under the effect of the force of a spring when the fuse comes into action. A sealing body, with a spring arrangement interposed, pushes a sealing head into the interior of a receptacle receiving the fuse. A two-armed lever is received on the sealing head, one arm covering a tripping mechanism which actuates a power switch. | 03-12-2009 |
| 20110095859 | MULTIPLE FUSE DEVICE FOR A VEHICLE - A multiple fuse device for a vehicle includes a circuit board with a battery-side bus bar portion and an alternator-side bus bar portion connected together by a temporary joint portion at a position apart from a fusing portion that provides charging current protection. An insulator housing is placed over the circuit board but the temporary joint portion is left uncovered by the insulator housing. A temporary joint portion is then at least partially removed. This partial removal may leave behind two temporary joint portion remnants, one on the battery-side bus bar portion, and one on the alternator-side bus bar portion. The temporary joint portion thus enhances the strength of the circuit board while the fuse device is being manufactured, which prevents the fusing portion from being accidentally deformed or broken during the device's assembly. | 04-28-2011 |

| 20100315192 | FUSIBLE LINK - A fusible link includes a fuse portion that has a first resistance portion and a second resistant portion which are formed of a fusible metal conductor. The first resistance portion has a fusible portion which is provided in proximity to a connecting portion of the first resistance portion with the second resistance portion and is adapted to be fused to be broken when the fusible portion is heated up by an overcurrent.

| 20100219929 | THERMAL FUSE WITH CURRENT FUSE FUNCTION - Disclosed is a thermal fuse structured in such a manner that a resistance heating element which generates heat according to an electric current is mounted within a case charged with a solid fusible material so that the fusible material is liquefied by heat of the resistance heating element caused by the external temperature and also by the current applied to a circuit, accordingly disconnecting the circuit. Since the resistance heating element is integrally formed in the case, the thermal fuse is capable of functioning as both a thermal fuse and a current fuse, disconnecting the circuit by both the external heat and the overcurrent. Especially, when the resistance heating element comprises a positive thermal coefficient (PTC) element capable of temperature measurement, the current flowing through the circuit can be measured. | 09-02-2010 |

| 20080297301 | HIGH VOLTAGE FUSE - A high voltage fuse is disclosed. The high voltage fuse is compact and includes a molded plastic housing that holds connecting terminals, a fuse element, and optionally, a spring between one of the terminals and the fuse element or thin wire.

The terminals may be mounted in separated parts of the housing, separated in some embodiments by the spring acting as an arc barrier. When the fuse element melts and the ends are pulled apart, the separation itself, or the arc barrier, prevents arcing between ends of the fuse element. In another embodiment, the housing itself furnishes a non-conducting plastic spring which urges the fuse link apart, the spring itself dividing the housing into two separate parts to prevent arcing. | 12-04-2008 |
