Thermal link
(Storage Heaters)
The thermal link is a type of heat sensitive white metal which melts at or above a given temperature. It is between two copper pins that allow connection to the power input supply and the input thermostat. If the heater exceeds a give temperature the link will melt and cut the power supply to the heater, affectively turning the appliance off. Because there are a number of different heater ratings the thermal links also vary in heat resistance, this is identified by the colour on the side of the link. If replacing a link be sure to get the correct one for your appliance. Never ever replace a link with a piece of fuse wire or copper wire.
