Do you want to understand how a Thermal Overload Relay (TOR) protects your electric motor? In this video, we break down the working mechanism, internal parts, and the science behind the Bimetallic Strip. In this video, you will learn: The Principle: How the bimetallic strip bends due to heat generated by high current. Overload Protection: How the relay detects excess current and trips the circuit. Internal Mechanism: A clear look at the heater coil, trip bar, and NC (Normally Closed) contacts. T
