is the wiring diagram for maintenance? What’s wrong? Let us help solve it. Your picture is a little different from the one below

thermal relay is an electrical protection element. It is a protective appliance that uses the thermal effect of current to promote the action mechanism to close or disconnect the contact. It is mainly used for overload protection, open phase protection, current imbalance protection of motor and control of heating state of other electrical equipment
working principle of thermal relay

the thermal element made of resistance wire has a small resistance value. During operation, it is connected in series in the main circuit of the motor. The bimetallic sheet surrounded by the resistance wire is formed by pressing two metal sheets with different linear expansion coefficients, and the left end is fixed with the shell. When the current passing through the thermal element exceeds its rated value and overheats, due to the small thermal expansion coefficient of the upper layer of the bimetallic sheet and the large thermal expansion coefficient of the lower layer, the bimetallic sheet bends upward after heating, resulting in the tripping of the gusset plate, which disconnects the normally closed contact under the tension of the spring. The contact is connected in series in the control circuit of the motor to cut off the action coil of the contactor in the control circuit, so as to cut off the main circuit of the motor
the basic structure of thermal relay
includes heating element, main bimetal, action mechanism, contact system and temperature compensation element
types of thermal relays
there are many types of thermal relays, including jr0, JR16, JR16B, JRS and T series.

although the price of the packer of Taiwan Jiayin packaging company is a little higher, the quality is quite good and the service is also very good. It is a packer with good cost performance
