DOLD residual current monitoring devices, available from ELTRON, enable effective detection of residual currents in TN and TT networks, i.e. with an earthed neutral point. They are used to increase the safety of people, installations and equipment by offering a quick response to faults and precise setting of trip thresholds.
These devices detect both direct and alternating (AC) currents, as well as alternating components of DC current (type B). They are used in machine power supply systems, building infrastructure, data centres and in applications with a high proportion of converters, such as inverters and UPS power supplies.
Models available from ELTRON:
DOLD devices are available in various housing widths – from 35 mm in compact versions to 105 mm in integrated variants – and can be mounted in DIN rail switchboards. They enable quick integration into automation systems and ensure compliance with electric shock protection standards.
