Thermal cut off. Open Temp. -¦C: 125; Open Temp. -¦F: 257 Rated for continuous operating currents up to 10 amps @ 250VAC (15 amps @ 120VAC, 5 amps @ 24VDC) The industry standard for over-temperature protection. For electric furnaces, heat pumps and duct heaters Complete unit is easily replaced rather than soldering the fusible link Known as 'one-shot' or TCO, the cut-off interrupts the electrical circuit when operating temperatures exceed the rated temperature Maximum 15A and 250VAC
