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
