Forgive my ignorance but what do you use the "3-pole circuit breaker" for?

I have only recently purchased the pro 'circuit breaker' version for $274NZD and it works great!

 

 

 

Good luck.

It was required to monitor multiple phases, as per the wiring diagram, but I suppose that's not the most common use case, so happy to sell for $150 without the circuit breaker included.

It looks like a 10A circuit breaker is needed to feed into the device so it can monitor voltage. The clippons only measure amps. Without measuring voltage, you won't get a VA or power consumed (watts).

 

The pro 'din' mounted version I have is feed from a single 6A MCB, to all 3 inputs, so each can measure voltage. (I am using it as a single phase, 3 circuit power meter).
