The temperature relay sensors TRE-201 are designed to protect built-in refrigerant-oil-resistant electric motors of compressors from overheating. The devices work in a set with temperature sensors - thermoresistors ST14-1.
The threshold of operation is determined by the temperature sensor resistance increase up to 2200Ohm, which allows to use it in any other systems of automatic regulation.
The mass of the device should be no more than 0.5 kg.
The average service life is not less than 10 years.
