TA45: 2 pole, push button actuated
• Thermal release
• Positively trip-free
The 2 pole, push button actuated version of the TA45 line of thermal
CBE’s can be used for various purposes. Basically it is a CBE for
automatic interruption of overloads with facilities for regular manual
ON/OFF switching operations under normal load conditions. It is
capable of interrupting moderate short circuit currents without the aid
of back-up protection.
A special version is available as a «CBE-switch», in which the means
for automatic overcurrent interruption (the bimetal relases), 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
1 or 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 reclosed manually.
• CBE switch with mechanical lock-out latch:
A spring loaded pin will trip the CBE if a protective cover of the
equipment 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 outfitted with an auxiliary contact
(changeover contact).
TA45 is positively trip-free. The rated current range is 0,1 to 20 A at
AC 230 V / DC 60 V. The CBE comes with snap-in mounting or
flange mounting. A locking device suitable for padlocks prevents
unauthorized switching ON of the CBE. The TA45 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.

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
