Earth-fault detector X72DB3

Overview
The X...DB3 series Type B earth leakage relay X72DB3 provides automatic detection of continuous (DC), alternating (AC) and high-frequency leakage currents. It offers continuous, immediate insulation-status monitoring via a multi-coloured display and is intended for 72 x 72 mm panel-mount installation. Suitable for industrial distribution boards and control cabinets with electronic loads, converters, PV inverters and charging stations where complex leakage currents may occur.

Note
This model has been superseded by the newer X72DB4 (replacement indicated on the product sheet).
