Function
DCT-C solid-core residual current transformers are designed to measure type A residual current. In the absence of faults, the vector sum of the currents is equal to zero. The DCT-C cores perform a vector sum of the currents in the circuit to identify any possible anomaly. They are designed for residual current protection and monitoring.

Advantages
Wide range of measurement
The DCT-C range offers a wide current range, from 36 to 630 A per phase, in accordance with IEC 61869-1.
High immunity
The accuracy of the DCT-C range comes from the integral winding around the core. In this way, it eliminates measurement errors related to the arrangement of the conductors.
Suitable for all cable diameters
The DCT-C range offers an unrivalled variety of sizes, ranging from 17 to 300 mm. Thus, it enables you to choose the most suitable core for the application.
Infinitely customisable
From primary current to transformation ratio, the technical specifications are fully customisable.
Universal
The secondary output voltage adapts to any differential and protection relays.
