Product Description

Residual Current Device Testers


Standard test ranges


  • 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/ 330 can also test RCDs rated at 10 mA and 1000 mA. All units offer DC testing of RCD’s. 
  • Test times for normal and Selective RCDs are: Normal Selective 1/2I 2s 2s I 300ms 2s 5I 40ms 150ms 
  • 5I tests are available on RCDs rated up to 100 mA. 
  • Polarity 
  • All RCDs can be tested at 0º or 180º 
  • Selective RCDs 
  • 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 
  • 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. Tough:- 
  • 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. 
  • Simple to use:- 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. 
  • Hands free use:–It hangs comfortably around the neck for hands-free use because the instrument is carefully balanced. DC sensitive RCDs 
  •  DC sensitive RCDs can be tested at 1/2I, 1xI and 5xI.  

Safety features:-

To protect the user and the tester from incorrect use the RCDT series all has an extensive range of features known as Megger Intelligent Safety System including:

LED connection indicators – show test lead connections and supply status

Safety Interlock – prevents unsafe connection of test leads

3 Phase safe - Even if the RCDT is connected across phases, the instruments will remain safe and not be damaged.

Test inhibit – If supply voltage exceeds 300V testing will be inhibited.

All the Megger RCDT300 series RCD testers meet or exceed the UK and International Wiring Regulations, including requirements of BS7671 and VDE 0413 parts 1 and 4, HD 384, IEC 364, NFC15-100, and NEN3140, ES59009, AS/NZS 3000 and EN 61557.

In addition the range meets the requirements of IEC 61010- 1 for safe connection to Category III supply (300 V Phase to Earth).

The new Megger electrician’s testers are simple, no fuss electrical testers that are tough, reliable and easy to use. Available in separate instruments, the series consists of the:

- MIT300 range - Insulation and continuity

- LT300 range - Loop testing
