RCMB121

To satisfy new standards including IEC 62752 and IEC 60364-7-722, the charging of electrical vehicles requires residual current sensors to avoid hazardous situations in cases where the vehicle battery (DC) is connected to the home power supply (AC). Generally, AC/DC sensitive residual current sensors can be used where direct current and alternating current circuits are directly connected and therefore AC/DC leakage currents can occur.

Typically type A residual current circuit breakers (RCCBs) are installed in private households. However, these RCCBs are to identify and deactivate DC fault currents. In order to charge an electric vehicle (EV) from a home power supply, a costly type B RCCB would be required to guarantee safety in the event of a DC fault current.

By using a benvac DI sensor integrated into an IC-CPD or wall box, customers can save the high costs of installing a type B RCCB to provide all-current sensitivity and electrical safety at low cost.

A single DI sensor simultaneously monitors all currents in phases and neutral conductors sensing AC/DC fault currents. The sensors can activate automatic shut-off in the event of hazardous electrical faults. As the residual currents to be monitored only occur in the event of electrical faults and are extremely low (mA), maximum measurement precision is critical. In addition, a fast response time is required to maintain safety features.
