RCMB131-01

The AC/DC sensitive residual current monitoring module monitors electrically earthed power supplies up to 300 V and connected loads up to nominal currents of 32 A for leakage and fault currents.

The module is intended for installation in distribution equipment such as PDUs (Power Distribution Units), outlet boxes or multiple socket-outlets and is supplied with DC 12…24 V.

The RCMB131-01 is designed for installation in PDUs and outlet boxes. The module can communicate with a master via an RS-485 interface via Modbus RTU.
