TF140DU-142 Thermal Overload Relay
TF140DU thermal overload relay - 66.0 to 142A
* Part number: TF140DU-142
* 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 TF140DU have trip class 10A
* 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
