Contactors in Australia

Shop contactors from AuscomTech. We stock practical contactor products for motor control, pump panels, fan control, automation systems, machinery, electrical control panels and industrial switching applications.

Whether you are switching a motor, controlling a pump, wiring a fan circuit, building a control panel, replacing a failed contactor or adding remote switching to industrial equipment, contactors provide a reliable way to switch higher-current loads from a lower-power control circuit.

Shop Contactors by Type

Our contactor range may include products such as:

• AC Contactors: Contactors used for switching compatible AC loads, motors, pumps, fans and control circuits.
• Motor Contactors: Contactors commonly used in motor starter circuits, pump panels, fan controls and machinery applications.
• Control Contactors: Contactors used for switching control circuits, auxiliary loads and automation panel outputs.
• DIN Rail Contactors: Contactors designed for mounting inside electrical panels and control cabinets.
• Contactor Accessories: Auxiliary contacts, mounting parts and related contactor accessories depending on current availability.
• Industrial Switching Components: Contactors and switching products used in automation, electrical control and industrial equipment applications.

Contactors for Motor Control, Pump Panels & Automation Systems

Contactors are commonly used in industrial control panels, pump systems, fan systems, machinery, conveyors, automation systems, lighting control, heating circuits and motor starter applications. They allow a control signal from a switch, relay, timer, PLC or controller to switch a larger electrical load.

Always check the coil voltage, contact current rating, motor power rating, AC or DC load type, number of poles, auxiliary contact requirements, mounting style, enclosure space, overload compatibility and wiring diagram before ordering.

Contactors vs Relays

Contactors and relays both switch electrical circuits, but contactors are generally used for higher-current loads such as motors, pumps, fans and industrial equipment. Relays are often used for smaller control signals, interface circuits and lower-power switching applications.

For interface relays, relay sockets and DIN rail relays used in control panels, browse our DIN rail relays and interface relays category. For thermal overloads used with motor contactors, browse our thermal overloads category.

Frequently Asked Questions

What is a contactor used for?

A contactor is used to switch an electrical load such as a motor, pump, fan, heater or lighting circuit from a control signal. Contactors are commonly used in automation and electrical control panels.

What is the difference between a contactor and a relay?

A contactor is generally used for higher-current loads such as motors and industrial equipment. A relay is usually used for lower-power control signals, interface circuits and smaller switching applications.

How do I choose the right contactor?

Check the coil voltage, load voltage, current rating, motor power rating, number of poles, contact type, auxiliary contact needs, mounting style and whether a thermal overload is required.

Do contactors need thermal overloads?

Motor starter circuits often use a contactor with a thermal overload or motor protection device to help protect the motor from overload conditions. The correct protection depends on the motor and application.

Can you help me choose the right contactor?

Yes. If you are unsure which contactor suits your application, contact AuscomTech with your supply voltage, coil voltage, motor power, load current, number of phases, control circuit details and any existing part numbers.
