FEATURES
Thermal cutoffs are designed to provide upper limit
temperature protection for many electronic products. Under
normal operating temperature, the solid pellet compresses a
spring which holds the star contact against the isolated lead.
When a fault temperature is reached, the pellet melts and
the circuit is opened permanently.
It is important to allow sufficient time to determine the
proper and best location for a thermal cutoff. The location
will affect the cutoff’s ability to protect your product. Placing
in the highest temperature area is usually best.

Approvals
The performance of the thermal cutoff requires proper handling during
installation for it to operate in its intended manner. These instructions are
intended to be used to reduce the risk of malfunction of the thermal cutoff
which may result from improper installation during forming of leads, splicing,
welding and soldering.
1. Bending Leads
Care should be taken when forming the Thermal Cutoff (TCO) leads. The
TCO leads must be supported 1/8” from bend and case; and 1/8” from bend
and epoxy. This will prevent the epoxy seal from cracking which may result
in premature degradation of the pellet. A close visual inspection should be
performed to make sure that the TCO leads have not been cut, nicked, folded
sharply, fractured or burned.
2. Mechanical Forces During Appliance Connection
a.
or pushing on the TCO leads. Care should be taken to avoid cracking or
chipping of the epoxy, which may result from sharp twisting, or bending of the
lead.
b. The TCO body must maintain its cylindrical shape to function properly.
Excessive clamping could cause denting or crushing of the TCO body, which
may lead to failure. X-ray and visual inspection of the TCO will determine if
the fuse body has been damaged.
c. Note that the TCO body is electrically live and must be insulated before
applying a metal clamp over the TCO body.
d. Care should be used when pushing the epoxy end lead to avoid the lead
being forced into the TCO body. This could result in a failure.
