CT toroidal clamp

Reference: 28000001

The CTSA016 toroidal clamp is a fundamental component in any solar installation, as it measures and controls all the electrical consumption of the installation and allows the inverter's production to be monitored.

The split-core design allows non-contact current measurement through the induction of the magnetic field, without the need to disconnect the primary cable. This method allows for safer and easier current measurement.

The size of the toroidal clamp makes it ideal for small spaces.
