RCMB131-02

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 RCMB131-02 is designed for installation in PDUs and outlet boxes. The module outputs the rms value of the residual current via a PWM output, which is read out and evaluated by a higher-level circuit.
