DESCRIPTION
The KLIXON® PD series thermal breakers are designed to protect wiring
and meet the harshest environmental requirements. The PD series are
weatherproof sealed for protection against moisture, dust, grease,
fuel vapors and other harsh environments. The PD series breakers
are compact, lightweight and designed to interrupt short circuits or
overloads, and combine trip-free protection with fast response time.
Typical applications are protection of wire and cable of accessory circuits,
equipment and battery protection in construction and off-road equipment,
marine, recreational vehicles (RV’s), mining, agricultural equipment and
electric (hybrid) vehicles.
The PD series is used in commercial and military applications.

DERATING CURVE
DIMENSIONS - PDM
Performance characteristics are based on room
temperature (77°F, 25°C). Consult Derating curve for ambient
temperatures significantly higher or lower than standard
room temperature.
Example: At 77°F (25°C) the device is calibrated to hold
at 110% of rated current (1) and trip at 138% of rated
current (2). At 140°F (60°C), the same device will hold
at approximately 92% of rated current (3), and trip at
approximately 120% of rated current (4).
