for AC circuit applications (they do not have recognition for DC circuit applications). These agency

electrical ratings can be used as a guideline when evaluating specific thermal cutoff applications.

However, the electrical and thermal conditions to which the thermal cutoff may be exposed in an

application may differ significantly from agency test conditions. Accordingly, customers should

not rely solely on agency ratings but rather must perform adequate testing on the particular

application to confirm that the TCO selected is appropriate for that application and will operate as

intended.

Important Notice

Users 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. For example, backup

controls have been incorporated in a number of applications for this reason.
