Introduction of thermal protector

A thermal protector is a thermostat made of two different alloys combined.

Thermal protectors may be referred to as thermoswitches or thermostats or thermal protection switches or temperature switches.
General requirements
The thermal protector is structurally and functionally integrated with the motor to form a thermal dynamic system, and the motor acts as a heater to affect the heating and cooling rates of the protector. The reliability and performance of the thermal protector shall be tested by installing the protector in the motor.
The requirements of this standard apply to a single motor or a motor and thermal protector in a series of motors.
When using a thermal protector, it must be determined whether the thermal protector is self-resetting or non-self-resetting. Generally speaking, self-resetting can be used unless the accidental restart of the motor may cause danger or injury to the user. heat protector. Examples of applications that require the use of non-self-replicating protectors are: fuel-fired motors, waste food processors, conveyor belts, etc. Examples of applications that require the use of self-replicating thermal protectors are refrigerators, electric washing machines, electric clothes dryers, fans, pumps, etc.
According to the nature of the action, it can be divided into normally open action and normally closed action.

Divided by volume: can be divided into conventional large volume and ultra-thin.
