Thermal overload relay TF65 and TF96
Thermal overload relays are economic
electromechanical protection devices for
the main circuit. They are used mainly
to protect motors against overload and
phase failures. Starter combinations are
setup together with contactors.
Description
– Overload protection – trip class 10
– Phase loss sensitivity
– Temperature compensation from -25 … +60 °C
– Adjustable current setting for overload protection
– Automatic or manual reset selectable
– Suitable for three- and single-phase application
– Trip-free mechanism
– Status indication
– STOP and TEST function
– Direct mounting onto block contactors
– Sealable operating elements

Application / internal function
The thermal overload relays are three pole relays with bimetal tripping elements (1 per pole). The motor current flows through
the bimetal tripping elements and heats them directly and indirectly. In case of an overload (over current), the bimetal
elements become bent as a result of the heating. This leads to a release of the relay and a change of the contacts switching
position (95-96 / 97-98). The contact 95-96 is used to control the load contactor.
The overload relays have a setting scale in Amperes, which allows the direct adjusting of the relay without any additional
calculation. In compliance with international and national standards, the setting current is the rated current of the motor
and not the tripping current (no tripping at 1.05 x I, tripping at 1.2 x I; I = setting current). The relays are constructed in way
that they protect themselves in the event of an overload. The overload relay has to be protected against short-circuit. The
appropriate short-circuit protective devices are shown in the table.
