Digital Earth Leakage Relays for type b applications X --- DB3 Series

The X...DB3 series earth leakage relays type B are designed to measure the DC, AC and high frequency leakage current. Having an LCD display it allows a continuous monitoring of the insulation state. This will allow for a program of preventive maintenance to avoid unexpected power outages.

The units are available in a DIN Rail mounting 36 mm version, and either a 48 or 72 mm panel mounting housing. The LCD backlight changes colour to indicate measure, alarm and trip status for quick and clear indication of network health. The three backlight colours are green, amber and red.

The TBD sensors for monitoring the combined AC and DC lines are available with a 28, 60 or 90 mm cable passing aperture. Care must be taken in the installation of the sensors to ensure cables pass in the centre.
