Sorry, there are no products in this collection.

As a result of technological advancement, industries now rely on labour-saving techniques and innovative products. To promote better productivity in the manufacturing industry, we at OZtherm bring a range of comprehensive products to meet the ever-changing demands and requirements of our clients across Australia. One such product is a solid state contactor.

It is used for controlling electrical loads without moving parts. The contractor manages contact bounce issues by switching both “ON” and “OFF” more quickly than mechanical relays. Our Temperature Sensor or versatile solid state contactors for heaters enable noise free and smooth operations.


The device allows the user to control high-current AC loads faster without wearing out for a longer time duration. The contractor is fully equipped with four screw terminals and a plastic cover to secure the terminals. The trigger voltage of the contactors ranges from 3 to 32VDC.


  • Long-term use
  • Reliable
  • Fast switching
  • Less electromagnetic interference
  • Compact size
  • Simplistic design
  • Optimised heatsink
  • Resilient to shock and vibration

The solid state contactors offer great speed, quick response and robustness. Ideal for aggressive atmospheres, the device comes in both single and three phase networks.

You can choose contactor devices based on:

  • Power system
  • Type of load
  • External temperature conditions

To choose the right contractor, first, determine the rated load current of the load and mains voltage. Then select a contactor with the same rated current as of the load. Also, remember to consider the design conditions while selecting a model.

The solid state contactors offer a wide range of applications. All you need to do is plug it in and connect and it’s ready to use. Once they are installed correctly, the contractors remain operational indefinitely. This way you won’t have to worry about expensive device replacements for a long time.
