Hey folks,

Does anyone know what current sensor this might be? Its from a Nissan Leaf contactor box, and the plug has three wires. Thanks!

I have attached a picture of a contactor from the unit and another angle of the sensor. The busbar is going through the sensor. I have no question that this is a current sensor, I was just hoping to ID it so that I could reuse it.
It's not a current sensor. It's almost certainly a contactor.

It's probably a special part for Nissan. There is some speculation as to it's specs here

You should be able to find out fairly easily all those linked are linear, so supply power and measure the output voltage with no current to get the offset, then pass a variety of known currents through to get the slope. All the known currents should plot on a straight line if it's anything like the rest of the range.
