CIRCUIT BREAKERS FOR EQUIPMENT
TA45: 3 pole, rocker actuated
• Thermal release
• Positively trip-free
The rocker actuated, 3 pole version with 2 protected poles is a
thermal CBE of the TA45 line, specifically designed to provide cost
effective protection of 3 phase motors against overheating in
accordance with EN60204 Part I (Electrical equipment for industrial
machines) in cases where the exception specified in this standard is
applicable.
A special version is available as a «CBE-switch», in which the means
for automatic overcurrent interruption (the bimetal releases), are
omitted.
Another available version of this line utilizes an under-voltage release
to protect persons against injuries caused by unexpected events like
the automatic restarting of motors after a power failure. This release
can be combined with the thermal release required for overcurrent
protection. Protection against injuries is also provided by another CBE
of this line, which prevents the starting of a machine should a
protective cover be removed from dangerous parts of the machine.
Available options:
• CBE for overcurrent protection
2 protected poles (thermal)
• CBE with undervoltage release:
The CBE will open automatically when the voltage drops
below the trip level. Only when the supply voltage has reached
the reset level, the CBE can be re-closed manually.
• CBE switch with mechanical lock-out latch:
A spring loaded pin will trip the CBE if a protective cover is
removed. The CBE can not be switched ON until the
protective cover is refitted.
• CBE with remote trip release:
The remote trip release permits the CBE to be tripped by a
external contact (sensor) energizing the trip coil.
• CBE with auxiliary contact:
All types of the line can be with an auxiliary contact
(changeover contact).
TA45 is positively trip-free. The approved current range is 0,1 to 12A.
We recommend to limit the current range to max. 8A at AC 400V.
For the current range 9 to 12A the voltage should be limited to AC
240V. The CBE comes with snap-in mounting. The rocker is available
in various colors and also with illumination. It is approved in all major
industrial countries and complies with the CBE-standard EN60934. In
conjunction with its accessories the TA45 product line of Schurter
paves the way for new unconventional applications.

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
