TF65 thermal overload relays – 22.0 to 67.0 A

Ordering details

Description
The TF65 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).
