Technical details

The two-channel residual current monitor meets the requirements of the DIN EN 62020 standard. A recurring insulation test can be omitted or at least limited. Typical places of application are the low-voltage main distribution (LVM) as well as the subdistribution boards (SSD) in grounded systems (e.g. TN-S systems). Across industries, the RCM 202-AB is a safe alternative when power interruptions due to a residual current device (RCD) or insulation resistance measurement are intolerable. Complete integration into the GridVis® software is possible. The device can be directly integrated via the RS485 interface.

Can be used as RCM at any point, e.g. DC systems, frequency converters, applications with increased fire protection requirements.
