We have added the Efergy XL Sensor to our web site.
Use this for cables over 12 mm diameter diameter and less than 19mm diameter.
This sensor allows up to 140 Amps whereas the standard sensor allows up to 90 Amps.
For single phase, you will need to purchase one of these.
For three phase, you will need to purchase three of these.
The sensor is about twice the size of a standard sensor and is mainly for use in industrial applications.
