Megger RCDT330-RCD Tester

The Megger RCDT330 tester can perform 1/2I, 1xI, and 5xI tests on RCDs rated at 10 mA, 30 mA, 100 mA, 300 mA, 500 mA & 1000mA on general and selective (time-delayed) & programmable RCD’s. Add this to the fact that you can download via USB up to 1000 test results with the supplied download manager software and you’ve got a RCD tester for every eventuality!

The RCDT330’s Data is stored in non-volatile memory, being retained when the instrument is switched off or batteries are exhausted. A Job reference number (up to 256) can be selected, allowing separate locations to be tested with the RCDT330 and easily separated when downloaded. A memory bar graph acts as a ‘Fuel Gauge’ showing how much memory has been used. Test results are downloaded to CSV (Coma Separated Variable) spreadsheets. The RCD T330 is Meggers’s flagship downloadable RCD tester.
