Construction of thermal relay the construction of thermal relay is quite simple.
Thermal overload relay.
A thermal overload relay works in the principle of electro thermal properties in a bimetallic strip.
Easy to create starters.

The function of a thermal overload relay used in motor starter circuits is to prevent the motor from drawing excessive current which is harmful to motor insulation.
It de energies the starter and stops the motor when excessive current is drawn.
The bimetallic strip gets heated up by the current directly or indirectly and when the current flow exceeds the set value it bends.
It is connected either directly to motor lines or indirectly through current transformers.
If the motor pulls too much electricity for an extended period of time the relay may flip and cut the power to the motor to prevent damage.
Reliable protection for motors.
These relays help to control the electrical current that goes to the motor to prevent it from overheating.
A thermal overload relay is a small electromechanical device that protects motors from overheating.
Thermal overload relays are economic electromechanical protection devices for the main circuit.
The thermal overload relay can make up a compact starting solution together with contactors.
It is placed in the motor circuit in such a way that the current to the motor flows through its poles.
