CT Clamp - small model 40A

PAY ATTENTION ! This is a smaller version of the standard CT clamp, you can measure this CT up to 40A. In addition, this is not a “Clip-on” model, so you must disconnect the appropriate cable to pass through the CT. This is only for the advanced electrician!

With this Clamp Terminal, zappi can make measurements on the phase cable (s) of the main fuse, for its protection, the consumption of the house. the surplus of own generation, but also for the yield of your energy system (solar panels or wind turbine).

With the 1-phase zappi and eddi, 1 CT is supplied as standard with zappi (with the 3-phase zappi, 3 CT terminals are supplied)

With an extra CT you can also display the yield of your solar panels and this can be read on the display. It is not necessary for correct operation to also place a CT on the inverter. This is only necessary to get a complete overview on the display (and via the HUB in the app) of all information about where the power is coming from or going.
