THERMAL CIRCUIT BREAKERS
THERMAL CIRCUIT BREAKERS
KLIXON® thermal circuit breakers are
compact, lightweight, protective devices
designed to repeatedly interrupt short circuits
or extended overloads in applications which
require precise, dependable operation plus
high resistance to shock and vibration. To
avoid nuisance tripping caused by harmless
transient or momentary overloads, these
circuit breakers feature an inherent thermal
time-lag characteristic. This enables
equipment to operate at maximum limits with
complete safety.
The heart of the thermal circuit breaker is the
KLIXON® metal disc. At a predetermined
overload, the heat caused by current passing
through the disc causes the disc to reverse its
curvature, or snap. This snapping action
separates the electrical contacts and opens
the circuit.
Trip curves provide the approximate time vs
current characteristics based on the ambient
“room” temperature of 77°F (25°C). Should
your application require performance
characteristics beyond the ambient “room”
temperature of 77°F (25°C), derating curves
provide additional data for ambient
temperatures significantly higher or lower than
standard room temperature.
KLIXON® thermal circuit breakers are
available in automatic reset and manual reset.
Some manual reset devices offer a switchable
feature whereby the contacts can be manually
opened to de-energize the circuit. For the
automatic reset device, the circuit stays open
until the disc cools and returns to its original
curvature, completing the circuit. For the
trip-free manual reset device, the contacts will
remain open until the device’s pushbutton is
depressed to reset the device and complete
the circuit.

• Meets 5000 amps @ 12VDC for interrupt capacity per ABYC E-11,
DC electrical systems of boats
DESCRIPTION
The KLIXON® F series thermal breaker series are designed for surface
mount applications and are available with automatic trip, manual reset,
trip indication, and a switchable option in a single device. The internal
components are enclosed in a vibration resistant, weatherproof, robust
casing to provide protection in the harshest environments found in
heavy truck, off-road, marine and construction applications. The F series
thermal breakers are designed to combine trip-free protection with fast
response time. Terminal studs are available in 1/4” or a larger 3/8” option
to allow higher torque connections and provide wider spacing for heavy
gauge wire lugs.

Approximate Time, Current Characteristics At 77°F (25°C)
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).

EXT 200 Series
Miniature Circuit Breakers
FEATURES
• SAE Type 2 (non-cycling) device
• Multiple bimetallic resistivities available
• Multiple terminal configurations available
• Metal encased
DESCRIPTION
The EXT 200 Series of mini remote reset circuit breakers are
commonly designed for 12 Volt DC wiring harness protection. The
device is ideal for the protection of circuits that may experience
momentary overloads and is often chosen as an alternative to
fuses, where nuisance replacement can be an inconvenience. The
EXT 200 can be mounted in the fuse block or elsewhere within the
wiring harness. This bimetallic device is sensitive to both over-
current and over-temperature fault conditions.
SPECIFICATIONS
• Nominal Operating Voltage: 12 Volts DC
• Typicale Voltage Drop at Operating Current: 200 mV max
• Current Rating: 5 to 35 amps @ 25ºC (in 5 amp increments)
• Typical Ambient Temperature Range: -40ºC to 85ºC

Amp Rating
The nominal electrical current in amperes
that the breaker will carry at room
temperature without tripping
Automatic
Reset
A device that opens by a combination of
overcurrent and elevated temperature,
with a design feature that allows the
breaker to cycle or continuously self reset.
Circuit
Breaker
A device designed to carry a specific value
of current and automatically open a circuit
upon overloads or short circuits.
Dielectric
Strength
A device’s ability to withstand a deliberate
application of pre–determined over–
voltage for a specified time.
Dielectric
Withstanding
Voltage
The maximum voltage that a switch can
withstand between specified points
without leaking current exceeding a
specified value.
Endurance
Refers to the longevity cycling of a circuit
breaker under less than direct short
conditions
Insulation
Resistance
The resistance offered by the insulating
members of a component part to direct
voltage tending to produce a leakage
current through or on the surface of these
members. Insulation resistance should
not be considered the equivalence of
dielectric withstanding voltage. Also:
Measures the resistance of the insulating
member of the device to a target voltage.
Manual Reset
A device that opens by a combination of
overcurrent and elevated temperature,
and remain open until manually reset into a
conducting state.
Maximum
Ultimate Trip
Current rating at which breaker must trip
within a certain period (usually 1 hour) at a
specified temperature.
GLOSSARY OF TERMS
Minimum
Ultimate Trip
Current rating at which breaker will not
trip within a certain period (usually 1 hour)
at a specified temperature.
Switchable
A design feature that allows a switchable
circuit breaker to function as a
conventional manual reset circuit breaker
and also has a mechanism, which when
exercised at the discretion of the user,
permits opening of the breaker internal
circuit to stop current flow. The breaker is
reset to its normal condition by the manual
rest function, whether tripped unattended
by a real fault condition or by the user.
Thermal
Circuit
Breaker
A circuit breaker that senses a current
overload based on thermal heating of the
sensing element.
Thermal
Derating
The effect of ambient temperature on
the trip characteristics of the breaker.
For example, as ambient temperature
increases, the amount of current required
to trip the breaker decreases.
Time-Current
Curve
An approximate graph showing the
minimum and maximum time a specific
breaker will trip at various degrees of
overload.
Trip Free
A design feature that makes it impossible
to hold the breaker closed against an
overload.
UL
Underwriters Laboratory
Voltage Drop
The voltage decrease across the breaker
due to internal resistance of the device.
Weatherproof
Circuit breakers designed such that
if immersed or submerged in fluid (for
example, water) no fluid shall infiltrate the
internal cavities or workings of the circuit
breaker.
