MI 3152(H) EurotestXC (2,5 kV)
Testing RCDs
7.7
Various test and measurements are required for verification of RCD(s) in RCD protected
installations. Measurements are based on the EN 61557-6 standard.
The following measurements and tests (sub-functions) can be performed:
Contact voltage,
Trip-out time,
Trip-out current and
RCD Auto test.
