Description
The TF69 thermal overload relays are economic electromechanical protection devices for the main circuit. They
offer reliable protection for motors in the event of overload or phase failure. The devices have trip class 10.
The thermal overload relays are three pole relays with bimetal tripping elements. 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 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).
–– Manual or automatic reset selectable
–– Phase loss sensitive acc. to IEC/EN 60947-4-1
–– TEST and STOP function – Trip indication on the front
–– Temperature compensation
–– Suitable for three- and single-phase applications
