Thermal relays consist of several key components, including a bimetallic strip, a coil, and contacts. When the current passing through the circuit exceeds a certain threshold, the bimetallic strip, which is made of two different metals with different expansion rates, bends due to the heat generated. This bending causes the coil to energize, which in turn opens or closes the contacts, thereby breaking or completing the circuit.

　　Types of Thermal Relays
There are several types of thermal relays, each designed for specific applications:
