TF42 thermal overload relays – 0.10 to 38.0 A

Ordering details

The TF42 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).
