Function
DCT-C solid-core residual current transformers are designed to measure type A residual current. If there are no faults, the vector sum of the currents is zero. DCT-C cores perform a vector sum of currents in the circuit to identify any anomalies. 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
thereby eliminates the measurement errors associated with the arrangement of the conductors.
Suitable for all cable diameters
The DCT-C ranges offers an unequalled variety of sizes, from 17 to 300 mm. This enables selection of the core most suitable 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.
