Abstract
A heavy-duty, time-delay fuse includes a pair of heat sinks having mutually facing, generally planar contact surfaces normally eutectically soldered to each other. A spring between the heat sinks is operative for urging the contact surfaces apart from each other in a direction generally perpendicular to the planes in which the contact surfaces lie in the event of an overload condition in which an overload electrical current causes a pair of fusible links to generate sufficient heat to melt the eutectically soldered interconnection between the contact surfaces after a predetermined time delay proportional to the amount of heat absorbed and dissipated by the heat sinks.
