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.

How moeller's overload relay works?

Moeller's overload relay works by monitoring the current flowing through a motor. If the current exceeds a set value for a period of time, the relay will trip and disconnect power to the motor, protecting it from damage due to overheating. This helps prevent the motor from drawing too much current for an extended period, which could be harmful.

What is thermal overload?

The load current is made to flow through the thermal overload relay, which is actually a bimetalic strip. Beyond a prespecified current the bimetalic strip tend to deflect due to heat (thermal effect) thus cutting off the circuit and hence it acts as an over load relay protection.


All motor currents flowing through either the forward or reverse contactors must flow through?

the overload relay. This allows the overload relay to accurately measure the current being drawn by the motor and provide protection in case of an overload condition. It ensures that the overload protection is effective and responsive to the motor's operation.


How do you check tripping of thermal overload relay?

there is a bi metalic strip is thre in thermal overload relay so when the currtent is high then its settings so that strip bend due to thermal and it touches the other side of the contact so when u touch the tester on that side u will find that its overload if u dont under stand contact me......
