250v 15a bimetal thermal protector for tailgate motor protection


HC02 bimetal thermal protectors are widely used in auto parts.Such as window wiper motors,seat adjustment motors,pedal motors and tailgate motors.When it comes to car tailgate motors, we should pay attention to the protection of the motor. The motor often has overload and overheating problems. If these problems often occur and are not solved in time, it is easy to reduce the life of the motor or even burn the motor. The most common way to protect the motor is to add a motor thermal overload protector.

The function of the thermal motor protector is that when the motor runs abnormally, for example, if the motor is stuck and locked, it will cause the motor to overheat, and the motor thermal protector will receive this signal and cut off the power to the motor, so as to achieve the purpose of protecting the motor, which is very effective.



1.Plastic housing design

The shell of the HC02 thermal protector is made of environmentally friendly plastic material PBT, which not only has good insulation, but also has better high temperature resistance and stability. Strictly comply with ROHS environmental protection standards.

2.High-quality chips imported from the United States

In order to make our products more accurate, reliable, synchronous, and more sensitive to temperature and current, our bimetal chips use raw materials imported from the United States.When your motor is overloaded, blocked, etc., HC02 thermal protector can quickly cut off the circuit and provide precise protection for your motor.

3.Small size

The size of each of our thermal protectors is very small, which is for the convenience of customers to install. Of course, the size can also be customized according to your requirements. As long as it meets your product, we will do our best to make it.

4.Contacts using AgNi alloy

The moving contact and the static contact are made of AgNi alloy, which can ensure a longer life of the thermal protector and a more accurate tripping time. The overload trip current value can be set according to your requirements, up to 30A. HC02 thermal protector trip time is very precise, within 4-10s.

Case analysis

With the development of science and technology, cars are becoming more and more intelligent. For example, the traditional method of opening and closing the tailgate of a car has been manually opened and closed for a long time. Now you only need to press the remote control, and the tailgate can be opened and closed automatically.

What technology achieves this function? The principle is simple:the micro-drive system is used for the push rod of the tailgate of the car. It acts on the gear of the electric push rod motor of the tailgate. It is composed of an inner tube and an outer tube through the main shaft drive. The push rod motor and the gear box in the inner tube drive a threaded spindle,the threaded spindle runs on a threaded nut fixed inside the outer tube. The electric strut pusher uses an electric spindle located in the motor inside the strut to open and close the trunk lid. The spring also assists in the lid opening operation.

tailgate motor HC02 tailgate motor thermal protector


Recently, Mr Li,the product manager of Zhejiang Zhenyi Auto Parts Company ,came to us and wanted to find a suitable thermal overload protector for the tailgate push rod motor. He needed double current and temperature protection, the temperature is 130°C, and the overload current is 20A.Therefore, we recommend HC02 series thermal protector and HC01 motor thermal protector to him. Both of these models can meet the requirements of Mr. Li. After testing, Mr. Li finally chose the HC02 series according to the installation environment.

HC02 thermal protector for tailgate motor has a plastic shell with better insulation, small size and can be directly connected in series in the circuit for protection, with fast tripping speed, accurate protection and better protection effect.
