Core balance transformers

Presentation

The installation of protection or signalling resources such as earth leakage protection relays

These enclose active conductors, providing the differential summation of vector currents and revealing leakage current.
The core balance transformers (toroids) proposed by SOCOMEC are suitable for differential relays RESYS M20/M40/P40. 
Closed (series W, WR and TFR) or opening (series WS) types, they suit all wiring configurations.
A special range is proposed for RESYS B470/B 471 and B 420 relays.
