OVERVIEW
ACEL618 Series
AC Earth Leakage Detection Unit
The ACEL618 Series is an AC earth leakage detection unit designed to monitor residual current in single-phase and three-phase AC electrical systems. Using non-contact current sensing technology, it detects current imbalances to support equipment protection and fault monitoring.
Featuring two independent detection channels, configurable warning and trip thresholds, and latching relay outputs, the ACEL618 provides flexible integration into railway power systems and industrial electrical installations.
