TEMPERATURE RELAY

The proposed temperature relay contains a casing made of insulating material, in which an open magnetic circuit with a permanent magnet and a fixed contact are installed. In the air gap of the magnetic circuit, a thermosensitive element is arranged, with the possibility to move, which is made of thermomagnetic material with a specified Curie temperature and used as the movable armature of a magnetic system. The thermosensitive element is fixed to a resilient plate that is coupled with a return spring with the possibility for the plate to move in the direction of closing and opening the contacts of the temperature relay. The movable contact of the temperature relay and a U-shaped stop are attached to the inside surface of the casing. The stop is used for adjusting the air gap of the magnetic circuit and for adjusting the movement length of the return spring.
