Residual current monitoring device RCM 202-AB
)
The two-channel residual current
monitoring device meets the requirements of the DIN EN 62020 standard. A
recurring insulation test can be omitted or at least limited. Typical
applications are low-voltage main distribution boards (LVMDB) and subdistribution
panels (SDP) in grounded systems (e.g. TN-S systems). The RCM 202-AB is a safe
cross-industry alternative if current interruptions due to a residual current
device (RCD) or an insulation resistance measurement cannot be tolerated. The
device can be integrated directly via the RS-485 interface.
