Klixon TH10, TH11 and TH21 Series
Self-hold 250V-16(2)A Thermal cut-outs
Series Specification Sheets (pdf)
Klixon has developed the electrical self-hold temperature cut-out in order to offer a non-self-resetting device suitable for high current applications, thus fulfilling the growing need for higher safety.
One ceramic pin has a layer of resistive material, functioning as a small heater when a voltage is supplied. The operating principle of the TH series simple and effective. A current flows through the resistive Klixon bimetal disc. When a fault condition occurs, the increased ambient temperature causes the bimetal disc to snap open the contacts. The resistive layer spots the voltage over the open contacts and a current flows through the resistor, generating sufficient heat to keep the contacts open. When the power is switched off, the device cools down to a safe temperature and the contacts will close.
Price: $17.50 each
