Toroidal current transformer CTE-60 004671610

Toroidal current transformer – precise measurements and installation protection

The CTE-60 toroidal transformer is an element used for safe and accurate current measurement in electrical circuits. This device, manufactured by ETI POLAM, finds wide application in both industrial, commercial and residential installations. Its construction based on the toroidal transformer principle ensures high measurement accuracy and galvanic isolation, which increases safety of use.

Construction and application

The CTE-60 transformer is characterized by a 60 mm diameter aperture, which allows its installation on wires of various thicknesses. It is a summing current transformer, which means it measures the sum of currents flowing through its aperture. It is widely used in energy consumption monitoring systems, in overcurrent protection circuits and for cooperation with various measuring and control devices. Thanks to its construction, it allows non-invasive current measurement – it does not require interrupting the circuit.
