Description

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.
