Microtemp Thermal Cutoffs

Microtemp Thermal Cutoffs from Therm-O-Disc offer an accurate, reliable solution to the need for upper limit temperature protection. Know as a thermal fuse, thermal link, or TCO, the MICROTEMP thermal cutoff provides protection against overheating by interrupting an electrical circuit when operating temperatures exceed the rated temperature of the cutoff.

The operating principle of the thermal cutoff is a electrically nonconductive pellet that under normal operating temperatures will hold the spring loaded contacts closed. When a predetermined temperature is reached, the pellet melts, allowing the compression spring to relax. The trip then slides the contact away from the lead and the circuit is opened. After the thermal cutoff opens the circuit it must be replaced. These devices are often referred to as "one shot" thermal fuses. All temperatures are in Celsius.

TESTCO does not provide service parts to the general public. Consequently, to receive an exact replacement part you must contact the Original Equipment Manufacturer (OEM).

Therm-O-Disc is a large manufacturer of bimetal thermostats, thermal fuses, and other devices. The majority of their products are custom made and proprietary for Original Equipment Manufacturers (OEM's).  We offer some standard configurations, however, the user must determine the suitability of the control for their application, including the level of reliability required, and are solely responsible for the function of the end-use product.  These controls contain exposed electrical components and are not intended to withstand exposure to water or other environmental contaminants which can compromise insulating components. Such exposure may result in insulation breakdown and accompanying localized electrical heating. A control may remain permanently closed or open as a result of exposure to excessive mechanical, electrical, thermal, or environmental conditions or at normal end-of-life. If failure of the control to operate could result in personal injury or property damage, the user should incorporate supplemental system control features to achieve the desired level of reliability and safety.

There are no express warranties that extend beyond the description contained herein. Please review our Terms & Conditions before ordering.
