Pulished on Nov. 03, 2026
Are you looking for a cost-effective, high-performance alternative to the Bender RCMB121 for your EV charger design? The IVY Metering MD0630 Series is the industry's leading Residual Current Monitoring Unit (RCMU). It strictly complies with IEC 62955(6mA DC/30mA AC detection), offering identical safety standards to Type B protection.

When designing earth-leakage protection architectures, electrical engineers often confuse two core components: the residual current monitoring relay (RCMR) and the residual current monitoring unit (RCMU). Although both detect leakage current, their roles at the system level are fundamentally different.

Nowadays, any public DC fast charger deployed in Europe must provide accurate and transparent billing based on the actual energy delivered (kWh). For EVSE OEMs planning to enter the EU market, integrating a DC energy meter that is both precise and absolutely tamper-proof into the charging unit has become the key to overcoming technical barriers.
