Known as a thermal fuse 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.

Operating Principle
of the MICROTEMP
TCO
The active trigger mechanism
of the thermal cutoff is an
exclusively formulated, elec-
trically nonconductive pellet.
Under normal operating
temperatures, the solid pellet
holds spring-loaded contacts
closed (see figure 1).

trip spring then slides the
contact away from the lead
and the circuit is opened
(see figure 2).
