The Thermal DF Series Thermal Cutoffs are single action devices that open when
a preset temperature is reached. They do not reset. The active component of a ther-
mal cutoff is an electrically insulated thermal pellet. This pellet holds a spring loaded
contact against a fixed contact under normal operating temperatures. (See Fig. 1)
When the preset temperature of the cutoff is reached, the pellet liquifies, the springs
relax, and the spring loaded contact is moved away from the fixed contact, opening the
circuit. (See Fig. 2) The DF Series is the right choice for applications requiring an inex-
pensive limit protector with 15A capability.
