Strong Points
Function
Residual core transformers, including the active conductors, establish the differential sum of the vector currents to detect leakage currents.
Closed ∆IC series models, these core transformers are suitable for all wiring configurations in new and existing systems.
Mounted on a DIN rail, plate or straight on the cable, these residual CTs adapt to any setup constraints for easier and faster wiring.
You need core balance transformers to implement differential relay protective or signalling units.

Advantages
Complete range
All dimensions and types are available for compatibility with busbar or cable configurations of all dimensions, for single-phase or three phase applications.
Optimum performance
Thanks to patented innovation, the conductors are perfectly centred in the residual CT to ensure accurate measurement and enhanced immunity to mains disturbances. It also enables direct mounting of the residual CT onto the cable.
High sensitivity
Socomec residual CTs can measure leakage currents from 3 mA enabling early detection of insulation degradation.
Clear alarm indication
The T-10 RJ12 adaptor integrates an alarm LED to quickly locate RCM alarms inside electrical cabinets.
Plug & Play
- Direct mechanical and electrical connections to the residual current transformer.
- RJ12 connection to the DIRIS Digiware R-60 for easy integration of the Digiware system.
