TF96-B thermal overload relays – 40.0 to 96.0 A

Ordering details

The TF96-B 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).
