Function

DCT-O split-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-O cores perform a vector sum of the currents in the circuit to detect any possible anomaly. They are designed for residual current protection and monitoring.

Conformity to standards

Advantages

Multiple mounting

The DCT-O range offers a variety of mounting options thanks to its versatile accessory. Whether on DIN rail or backplate (front panel), DCT-O units adapt to your specific needs.

High immunity

The DCT-O range is differentiated by its full wrapping around the core, providing unrivalled accuracy by eliminating inaccuracies related to the layout of the conductors. In combination with Socomec's patented centring system, this combination ensures absolutely reliable electrical measurements.

Secure closure

The "One Click" system guarantees fast and reliable closing, even under heavy mechanical conditions.

Faster connection time

Thanks to its quick connection kit, the DCT-O range makes it quick and easy to connect secondary wires, providing quick and easy installation.

Infinitely customisable

The specifications are fully adjustable, enabling full customisation, from primary current to transformation ratio.
