Small bimetal Motor overload protector
Usually, 5AP/2MP/6AP is used as the motor overload protection device. When in use, connect the thermal element (three-phase or two-phase) of the overload protector in series to the main circuit of the motor. Connect the main contact of the thermal relay to the contactor coil circuit in series.
The necessity of motor overload protection:
When the motor is running, it is generally allowed to overload for a short time (the output power exceeding the rated value is called overload). Однако, if the overload time is too long and the temperature rise of the motor exceeds the allowable value, it will cause insulation aging, shorten the service life, and even burn the windings in severe cases. Therefore, in order to prevent damage to the motor due to long-term overload operation, the overload time must be limited. This protection is overload protection.
Usually, 5AP/2MP/6AP is used as the motor overload protection device. When in use, connect the thermal element (three-phase or two-phase) of the overload protector in series to the main circuit of the motor. Connect the main contact of the thermal relay to the contactor coil circuit in series.
When the motor overload operation, the current is increased, the heating element temperature rises, the bimetal gently curved, and thus exceeds the predetermined value, and finally open the normally closed contacts, so that the motor coil is deenergized. So as to cut off the power of the motor and avoid the motor from being burnt due to long-term overload operation.

What Is A Thermal switch?
Thermal switch is based on the working environment of the temperature changes, physical deformation occurs inside the product, a control element which is automatically turned on or off, also known as temperature control switch, thermal protection, temperature controller and so on. Commonly used temperature control methods are:
CREEP ACTION THERMOSTAT, MOTOR PROTECTOR
VA1/VAA1 replaces the PEPI creep action thermostat bimetal thermal protector with higher current sensitivity:
[The PEPI CREEP ACTION THERMOSTAT] VAA1 adopts bimetallic control, and the inside is a low-resistance circuit with gold-plated contacts. Constant temperature control design and small size. It is suitable for electric blankets, electric heating pads and all kinds of small household appliances that require constant temperature function.
klixon 3MP+PTC overload protector for motor power-off reset
3MP+PTC current overload protector (with power-off reset function)
PTC self-sustaining function: When the overload trips, it can be automatically turned on after cutting off the power supply.
With delay protection function. It is produced with the proprietary technology of Texas Instruments KLIXON ® in the United States.

The function of automatic cut-off switch to prevent overheating
The automatic cut-off device against overheating is an electronic technology protection device. It can automatically cut off the power supply when electrical equipment overheats to avoid damage and danger caused by overheating of electrical equipment. In modern electrical equipment, automatic cut-off devices to prevent overheating have become an indispensable safety measure.
