Abstract: Redundant fuse wire apparatus and redundant release devices, such as those used to release deployable appendages, such as solar array and reflectors disposed on satellites, and the like. An exemplary redundant release device comprises a restraint release mechanism having one or more restraint release arms, a redundant release device comprising a segmented spool having a plurality of segments that are constrained from separating by spring restraint tape releasably secured to the restraint release arms, a redundant fuse wire assembly comprising primary and redundant positive contacts, a common negative contact, primary and redundant fuse wires respectively connected between the primary positive and common negative contacts and the redundant positive and common negative contacts that respectively wrap around the opposed positive contact and the restraint release arms, and an electrical power source for heating and severing the fuse wires.

Abstract: The invention relates to a conductor fuse (1) for an electrical or electronic device, comprising a first and a second connecting region (2a, 2b), a blow region (3), which is arranged between the first and second connecting regions (2a, 2b) and does not extend linearly, and a continuous cover region (4), which is arranged at least partly over the first and second connecting regions (2a, 2b) and the blow region (3), wherein the blow region (3) and the cover region (4) are arranged relative to each other such that at least one tripping region (3a) of the blow region (3) is not covered by the cover region (4), but delimited on both sides by the cover region.
