Metrel MI-2121-AUS RCD Tester

RCD Tester & Isolation Transformer

The MI 2121-AUS is Australia’s fully compliant RCD tester meeting all of the requirements of AS3760 & AS3190, as well as providing test result logging.

From the trip time accuracy of +2.5% to the test current accuracy of +5%, the MI 2121-AUS has been designed and built from the ground up to comply to all the mandatory Australian RCD tester requirements.

The MI-2121-AUS was awarded the Australian Defence Forces RCD Tester Tender 2004-2007 after an extensive review of RCD testers on the Australian market.

RCD testing is an important and sometimes neglected aspect of AS/NZS3760:2003. Regular testing of fixed and portable RCDs is required to ensure their operation should leakage to earth occur in the workplace.

Also available is the PRO-ITX Isolation Transformer for testing portable RCDs.

Emona PRO-ITX Isolation Transformer

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.

Emona’s 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 mains power outlet, plug the portable RCD under test into PRO-ITX, connect RCD tester to portable RCD under test and test the RCD.
