Monitoring of residual current monitoring type A to B+
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.
