Over Load Relay Features:

In order to prevent electric motors from overheating, an electrical component known as an overload relay is utilized. Therefore, it is essential to ensure sufficient protection for the motor. To safely operate an electric motor, circuit breakers, fuses, or overload relays can be employed.

Types Overload Relay

Thermal Overload Relays: To detect high current flow and initiate a response to interrupt power, use a bimetallic strip or a heating element. Electronic Overload Relays: Using precise and programmable trip settings, these devices use electronic circuits to monitor current levels and protect against overloads. Magnetic overload Relays: These devices trigger when a current flows over a preset threshold because they rely on the magnetic force produced by the current flowing through a coil.

Applications of Overload Relay

• The applications of an overload relay encompass the following:
• It is widely employed for safeguarding the motor.
• It can be utilized to detect both instances of overload and instances of faults, subsequently issuing trip commands to activate a protective device.
• This relay has evolved into microprocessor systems and solid-state electronics.

These relays deactivate the device whenever it draws excessive current. The overload relay is an electrical and mechanical device used to protect circuits from overloading. Its main purpose is to safeguard motors in case of phase failure or excessive load. What role does the overload relay serve?
