No, I'm afraid not. We use this Infinity Sensor for double pulse testing at the values you state, but not for continuous switching, since it would overheat. Also, it's worth considering that the Infinity Sensor is for looking at fast switching edges, not the whole waveform. For that it would be better to use a Rogowski coil, so as those offered by PEM Ltd.
I could imagine that working. Let us know how you get on. You could try a shunt measurement on the secondary side current transformer instead of buying our sensors.
