Protag Isolation Transformer, For Use With MI2121-AUS

Have you had problems testing portable RCDs because you keep tripping the RCD on the main switchboard? Then you need an isolation transformer. An isolation transformer is used for testing portable RCDs. It enables service providers to trip a portable RCD without tripping the main switchboard RCD’s.

The PRO-ITX Isolation Transformer is unique in that it allows 30mA *2 or *5 current tests which are called for in certain parts of AS3760 and AS3190. The PRO-ITX is the best choice to meet Australian Standards and compliments Emona’s MI2121-AUS tester.

The PRO-ITX is also thermally protected from overload short circuit currents, comes with a 1.5m long mains lead and integral handle.

To use, simply plug PRO-ITX into the mains power outlet, plug the portable RCD under test into PRO-ITX, connect RCD tester to portable RCD under test and test the RCD.
