Megger RCDT320 RCD Tester

The RCDT300 series can perform 1/2I, 1xI and 5xI tests on RCDs rated at 30 mA, 100 mA, 300 mA and 500 mA on general and selective (time delayed) RCDs. The RCDT320 can also test RCDs rated at 10 mA and 1000 mA. All units offer DC testing of RCD’s.

Selective breakers have a time delay in tripping. When selected, trip test times are extended and a 30s delay is allowed between the measurement of the fault voltage and the application of the test current.

Designed to take the bashing that testers receive on site, the Megger RCDT testers are rubber armoured. The rigid display cover folds right out of the way during testing and locks down to protect the display when it is finished. No buried functions mean it is obvious how to use the Megger RCDT.
