Abstract
A protection device for interrupting power to a load connected to a pair of terminals when the temperature of a terminal exceeds a predetermined threshold comprises an alloy having a eutectic at the predetermined threshold and a neon gas-filled glow tube electrically coupled in parallel with the thermal fuse. The thermal fuse is electrically serially connected between the terminal and the load and thermally coupled to the terminal so that an excessive temperature rise at the terminal causes the fuse to melt, thereby removing power from the load and causing the glow tube to be lit.
