TF140DU thermal overload relays – 66 to 142 A
Ordering details

Description
The TF140DU 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 10A.
The thermal overload relays are three pole relays with bimetal tripping elements. The motor current flows
2CDC231012F0012 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
TF140DU – 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
