How to choose a motor thermal protector
Sep 23, 2022|
View:552Overload means that the operating current of the electrical equipment exceeds its rated or allowed current. Overload can easily cause the temperature of the line and electrical equipment to rise, damage the insulation of the electrical equipment and lines, and cause safety hazards in the operation of the equipment. Therefore, certain measures need to be taken to protect some important equipment and lines, which is called overload protection. This device is calledMotor thermal protector。
In the field of communication power supply, air switches and fuses are usually used to implement overload protection functions. Placing an air switch or a fuse in the power supply line can achieve the overload protection function. The implementation methods of these two devices are different.

Air switch type motor thermal protector: When the current flowing through the air switch is greater than its rated current, the air switch will automatically trip. The air switch is a reusable device and can be reused by reclosing it after tripping.
Fuse typeMotor thermal protector:When the current flowing through the fuse is greater than its rated current, the fuse will break. The fuse is a one-time device and cannot be used again after it is blown.
The above is some introduction on how to choose a motor thermal protector. Changzhou Ainuo Electronic Technology Co., Ltd. is a manufacturer of motor thermal protectors.
