The Megger RCDT330 Residual Current Device Tester (RCDT) is designed for standard, dc, selective, and programmable RCD testing to IEC61010-1. The unit enables testing on 110 V centre tapped supplies, and performs 1/2I, 1xI, and 50xI tests on RCDs rated at 10, 30, 100, 300, 500, and 1000 mA on general and selective (time delayed) RCDs.
When combined with the Megger RCTD330 download manager software, users can download up to 1,000 test results for analysis and data storage via a USB interface. The internal data is stored in non-volatile memory, and is retained when the instrument is switched off or the batteries are exhausted. The RCDT330 is 3-phase safe and weatherproof to IP54.
