TF140DU thermal overload relays – 66 to 142 A

Ordering details

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 cur-
rent flows through the bimetal tripping elements and heats them directly and indirectly. In case of
