MICROTEMP^® thermal cutoffs are recognized by the major approval agencies throughout the world
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.
