A release apparatus includes a coiled restraining wire with each end attached to a corresponding fuse wire. The fuse wires are supplied with respective actuation electric currents by respective independent current sources. Flow of actuation current through a fuse wire causes that fuse wire to break; breakage of either one or both fuse wires allows the restraining wire to partially uncoil and allow the release apparatus to transition from a retained condition to a released condition, by allowing disengagement of retention members from a release member that can then move out of the release apparatus. The release apparatus can be employed to attach a deployable component to a satellite or spacecraft, and can be readily repaired, refurbished or reset for repetitive ground testing.
