The practical effect of the over-current over-temperature protector supplied by the manufacturer is mainly reflected in the fact that when the appliance is operating abnormally, the surrounding temperature will be too high. At this time, the installed over-current over-temperature protector will cut off the circuit to prevent electric shock accidents, thus protecting the operation of the appliance.

After being cut off, when the temperature cools to a relative level, the over-current over-temperature protector's resistance will automatically reset, hence it is called an over-current over-temperature protector. The over-current over-temperature protector supplied by the manufacturer responds quickly and resets faster. Let's understand its general application requirements.

1. When using, first determine whether the over-current over-temperature protector supplied by the manufacturer is self-resetting or non-self-resetting. Generally speaking, unless there is a possibility of risk or harm to the user due to an unexpected restart of the motor, self-resetting can be used. Cases that require non-self-resetting protective devices include: gasoline engines, waste food recyclers, conveyor belts, etc.

2. During normal operation, the over-current over-temperature protector's resistance is in a free state, and the contact points are closed. When the temperature rises to the action temperature value, the heat stress caused by the heating of the wear-resistant pipe component will quickly act, opening the contact points and cutting off the power circuit, thus providing thermal protection.

3. The motor is structurally and functionally integrated to form a thermal dynamic system. The motor, as a heater, affects the heating and cooling speed of the over-current over-temperature protector supplied by the manufacturer. To ensure stable reliability and performance, the over-current over-temperature protector should be installed in the motor for testing.

Due to the good protective effect of the over-current over-temperature protector, it is widely used in many devices.
