The TDC and TDA series are current transformers designed for use with [Type A-F Earth Leakage Relays].
They must be installed with all single- or three-phase network conductors (phases and neutral, if present) routed inside the core. The protective conductor (PE or PEN) (for TN-C systems) must be located outside the core. The connection between the transformer and the leakage current relay must be made using the shortest possible length of shielded cable (shield grounded at one end) and routed at a significant distance from power circuits to minimize coupling interference and voltage drops on the resistances of the supply conductors.
