Overload Relay Diagram
An overload relay is a device used to trip/indicate a condition of overload (over current) in electrical equipment and thus protect it. We can also call it an overload protection relay. Overload Type Relay Overload Relay Working/Functioning

Siemens Overload Relay Wiring Diagram Cocraft
Overload relays are devices that protect electric motors from overloads and phase failure. When the motor is overloaded, it detects this and terminates the power flow, preventing the motor from overheating and winding damage. It can also protect the motor from phase loss/failures and phase imbalance, in addition to overloads.

overload relay has no power contacts and cannot disconnect the motor by itself. The control circuit contact must be wired in series with the coil of the contactor so that the contactor will de-energize when an overload occurs. Square D manufactures three types of overload relays, the melting alloy, the bimetallic, and solid state.

Step-by-Step Instructions for Connecting a Thermal Overload Relay. Step 1: Start by identifying the terminals on the thermal overload relay. Typically, there are three terminals: L1, L2, and L3. L1 and L3 are the line terminals, while L2 is the load terminal. Step 2: Ensure that the power supply to the motor is turned off.
