Page 50: Residual Current Device (Rcd) Testing
The MFT-X1 has a limit of 1000 mA for any test selected. With some higher current RCDs and especially type A or type B RCD, the range of tests that you can carry out is restricted. For example, the MFT-X1 cannot perform 5 x I tests on RCDs with a 300 mA rating or higher, as this would require a test current of 5 x I or 5 x 300 mA = 1500 mA, exceeding the 1000 mA limit. -
Page 51: About The Rcd Tests
For this test, the instrument uses a current equal to twice the rating (2 x I) of the RCD under test. The RCD should trip within 150 ms. When the RCD trips the test stops and the instrument shows the actual trip time. If the RCD fails to trip, the test stops after 150 ms, and the display shows >150 ms. www.megger.com MFT-X1... -
