General product description DACT series differential current transformers are especially sensitive current transformers for logging the smallest AC currents. In combination with suitable RCM measuring devices, they allow the logging of the smallest sinusoidal residual currents which escape to earth or through other paths in the event of a fault.

Transformer mounting DACT 60/DACT 120 DACT 60 DACT 120 Installation instructions When installing the transformers, the individual cables must be led through as shown. In general, protective earths present must not be led through the differential current transformer. In general, it should be ensured that all cables (phase and neutral conductors) are led through the transformer.

Installation instructions (continued) cable In order to prevent a magnetic effect on the differential current transformer, a bend in the cables being measured may occur only at a specific distance from the transformer.
