Note 1.Hereinafter referred to as "thermal protector". Note 2.The device carries the current of the motor and is sensitive to the current and/or temperature of the motor. 3.3 A device that acts in response to overheating and/or overloading of motor windings to cut off power to the motor. When it cools down to the reset temperature, it can restart Turn on the motor power. 3.4 A device that acts in response to overheating and/or overcurrent in the motor windings to cut off power to the motor. Under normal working conditions, if there is no manual operation The motor cannot be turned on again. 3.5 rated open temperature ratedopentemperature The thermal protector does not carry any current, or only the signal current passes through it, and the disconnection temperature value is measured under the condition of a certain heating rate. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22762-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 22762-2022_English as soon as possible, and keep you informed of the progress.
