Power cycled unit via circuit breakers several times.
Thermal cut out meaning.
It is available in two varieties.
As per iec standard the definition of thermal cut out and thermostat is as following.
Thermal cutout definition is a protective device for automatically opening an overloaded electrical circuit because of excessive rise of temperature.
Temperature sensing control intended to keep a temperature below or above one particular value during abnormal operating conditions and.
This safety feature halts the temperature climb before it can burn up the motor.
Thermal protectors can also be built into the windings see the illustration below.
The applications of and need for electromechanical thermal switch devices are broad and cover a huge diversity of industry applications.

Looking for thermal cutting.
The thermal fuse is a consumable.
A thermal fuse is a cutoff which uses a one time fusible link unlike a thermal switch which may automatically reset itself when the temperature drops the thermal fuse is more like an electrical fuse.
Thermal cutout in low stage occurs when trying to start up in low stage.
That is when inside temperature goes above inside set point temperature high stage starts up.
If high cool latch is set to 80 a c works perfectly in high stage when outside temperature is above 80 degress.
In single phase motors up to a given motor size around 1 1 kw it can be mounted directly in the main circuit to serve as an on winding protector.
The thermal protection is present to turn the motor off when excessive heat is generated within the motor circuitry.
By cutting off electrical power at certain temperatures this type of device protects the other components of the circuit from damage.
I m getting constant thermal lockouts on both high and low stages.
Many end engineers and purchasers do not understand the difference between thermal cut out and thermostat switch.
When inside temperature reaches set point temperature a c shuts down.
The term thermal cutoff switch generally refers to how the switch is used ie.
The thermal protector consists of one or more heat sensing elements built into the motor or motor compressor plus an external control device.
People are always confused to the concept.
They operate as a sensitive power cut out for both single and three phase motors.
A group of processes to sever metals by melting or by chemical reaction of oxygen with the metal at elevated temperatures explanation of thermal cutting.
A thermal cutoff is a device used to break an electrical circuit when it reaches a certain temperature.
A single use device that cannot be reset and must be replaced when it fails or is triggered a thermal fuse is used when the overheating is a result of a rare occurrence such as failure requiring.
