Wiring Diagram Thermal Overload Relay
An overload relay has two basic parts: A heater element that is connected in series with the power line to the motor. All current drawn by the motor must pass through the heater element. A set of normally closed contacts
Overload Relay Principle of operation YouTube
The electronics accurately identify excessive current or phase loss and react to the condition with greater speed, reliability and repeatability than a traditional electromechanical device. How do you know your overload is working? Single blink: Normal operation Double blink: Fault condition developing
Wiring Diagram Thermal Overload Relay Diagram
An overload relay is a device that protects an electric motor against overloads and phase failure. It senses the overloading of the motor and interrupts the power flow to the motor, thus protecting it from overheating and winding damages. Apart from overloads, it can also protect the motor from phase loss/ failures and phase imbalance.

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.

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
Overload relay and contactor wiring connection YouTube
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.
