Product description

At Western Automation we have spent over 30 years developing the highest quality RCD technology on the market today. Our RCD technology provides our customers with a superior and safe product that is continuously evolving to meet the needs of our customers and markets.

While our technology is somewhat complex it is based on the basic principles of how to detect a residual current. This is done with a current transformer which detects the difference between the currents flowing in a number of conductors. The current flowing to a load must equal the current flowing back from the load. If this is not the case, a potentially dangerous residual current will be flowing somewhere in the installation.

Under non fault conditions the current flowing to a load will be equal to the current returning from the load, and these two AC will flow in opposite directions when they are passed through a transformer with the result that their vector sum as seen by the transformer will be zero. While the load current could be 20 amps or even 60 amps, the transformer will still see zero current because the same amount of current is flowing in both directions.

At Western Automation we use the highest quality components and materials in our current transformers (CTs) to ensure that various ranges of currents are effectively detected. For example, if we are detecting currents from 1 milliamp to 100 milliamps we can ensure the transformer gives the correct output that is proportionate to the differential current. While the current is consistent in terms of proportionality it is also consistent in terms of temperature variations, from ranges of -25 degrees Celsius to +50 degrees Celsius. The quality of components we use in product development is an integral part of our process at Western Automation.

Our technology starts with the use of high quality components. Everything that goes into our technology is independently tested and verified.
