The RCDT300 series RCD Testers can perform 1/2, 1xI & 5xI tests on RCDs rated at 30 mA, 100 mA, 300 mA and 500 mA on general and selective (time delayed) RCDs. The RCDT320/ 330 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.

Touch voltage is measured at the start of the RCD test. If enabled it is displayed on the analogue arc on completion of testing. Touch voltage inhibit is selectable from 25 V or 50 V. Megger Range of RCDT300 Series RCD Testers are 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.Colour coded ranges help test range selection, reducing test times and fault location. A user guide in the lid provides all the basic information.
