Mr Woodgate, I have noted a CTL decision for IEC 60335-1 that seems to indicate that CECC 42200 certification is also acceptable. Also applicable to 60950-1 ?
Also, I am looking a the spec sheets for several IEC 61051-x certified MOVs and have noted that the rated voltages do not seem to correspond to the 120% requirement. Did the answer to the below question provide some insight into this requirement ? Thanks much.
