MICROTEMP
thermal cutoffs
®
from Therm-O-Disc offer an
accurate, reliable solution to
upper limit protection.
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.
MICROTEMP
®
Features
• One shot operation cuts
off electrical power.
• Current interrupt capacity
up to 16 amps @ 250VAC
(25 amps @ 125VAC).
• Low resistance
• Compact size
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).
G4 SERIES MICROTEMP
®
TCO
CLOSED CIRCUIT
Grey area shows current patch
Figure 1
When a predetermined
temperature is reached, the
®
pellet melts, allowing the
barrel spring to relax. The
trip spring then slides the
contact away from the lead
and the circuit is opened
(see figure 2).
G4 SERIES MICROTEMP
®
OPEN CIRCUIT
Grey are shows current patch
Figure 2
Once a MICROTEMP
mal cutoff opens a circuit,
the TCO needs to be replaced.
This replacement procedure
must include correction of
the fault condition before
the product is operated
again.
