CIRCUIT BREAKERS FOR EQUIPMENT
T13 Series
• Thermal release
• Positively trip-free
• Reset or manual actuation
• Manual trip lever
The T13 series of circuit breakers for equipment (CBE) consists of
single-pole, thermally operated devices intended to provide protec-
tion against damage due to overcurrent conditions.
The T13 was specially designed for use in markets where the back-up
breakers in the building installation may not rip instantaneously below
currents of 400 A. This applies, for instance, for North America. To
provide a protection ensuring fitness for further use after interrupting
a short circuit in conjunction with the available back-up device, a CBE
with a breaking capacity of at least 400 A is required.
The T13 not only has such a high breaking capacity, but offers also
a wide rated current range, excellent conditional short circuit capacity
and double-insulation for parts accessible in normal use.
Typical applications are the protection of single phase motors, internal
wiring, power supplies, rectifiers and transformers.
Available options
• Threaded neck type
• Snap-in type
• For resetting only or resetting plus manual trip with
separate trip lever
• Terminals: Quick connect- or screw clamp terminals
• Setting indication on the reset button indicates the position
of the contacts

Tripping characteristics
Effect of ambient
temperature
The unit is calibrated for an ambient tem-
perature of +23°C. To determine the rated
current for a lower or higher ambient
temperature, use a correction factor from
the table below:
