How overload relay works?

Answer 1

An overload relay is like a bodyguard for your motor. Its job is to protect the motor from overheating if it’s working too hard.

Here’s how it works, step by step:

⚡️ Motor draws current — When the motor runs, it pulls electricity from the panel.

📈 Too much current? — If the motor has to work harder than normal (maybe the machine is jammed or overloaded), it starts pulling more current than it’s supposed to.

🌡️ Overload relay feels the heat — The overload relay senses this extra current and starts getting warm.

⛔️ Relay trips and shuts down the motor — Once the relay gets too hot (because the motor is working too hard for too long), it trips — cutting power to the motor to protect it from damage.

Answer 2

An overload relay is fundamentally a board that protects the relay from overloads. It works on the science of being an AC inductor..

Answer 3

When overload in the line occur,the large amount of current flows in the line this will lead to the send trip signal from relay to circuit breaker
