Shop Thermal Overloads by Type

Our thermal overload range may include products such as:

• Motor Thermal Overloads: Overload protection devices used with suitable contactors and motor starter circuits.
• Contactor Overload Relays: Thermal overload relays designed to mount with compatible contactors depending on model and frame size.
• Adjustable Overload Relays: Overloads with adjustable current settings to suit the rated motor current.
• Manual / Auto Reset Overloads: Overload relays with reset options depending on the product design.
• Motor Protection Components: Supporting products used in motor control panels, pump panels and automation systems.

Thermal Overloads for Motors, Pumps & Control Panels

Thermal overloads are commonly used in motor starter circuits to help protect motors from overload conditions. They are often paired with contactors in pump panels, fan controls, conveyors, machinery, compressors and industrial control systems.

Always check the motor full-load current, overload current adjustment range, contactor compatibility, phase configuration, reset type, trip class, auxiliary contact arrangement, mounting style and wiring diagram before ordering.

Thermal Overloads vs Contactors

A contactor switches the motor or load on and off. A thermal overload is used with the contactor to help protect the motor from sustained overload conditions. In many motor starter circuits, both parts are used together.

For contactors used with motor starter circuits, browse our contactors category. For variable speed motor control, browse our variable frequency drives category.

Frequently Asked Questions

What is a thermal overload used for?

A thermal overload is used to help protect an electric motor from sustained overload conditions by tripping the control circuit when the current exceeds the set range for too long.

Is a thermal overload the same as a contactor?

No. A contactor switches the motor on and off. A thermal overload provides overload protection and is often used together with a contactor in a motor starter circuit.

How do I choose the right thermal overload?

Choose a thermal overload based on the motor full-load current, adjustment range, contactor compatibility, supply type, reset method, trip class and mounting style.

Do all motors need a thermal overload?

Many motor control circuits require suitable motor protection, but the correct protection depends on the motor, application, wiring rules and equipment design. Always follow applicable electrical standards and qualified advice.

Can you help me choose the right thermal overload?

Yes. If you are unsure which overload suits your application, contact AuscomTech with your motor power, voltage, full-load current, number of phases, contactor model and any existing part numbers.
