Product Highlights


Installation alone can help EV chargers meet residual current protection requested by IEC 61851-1 & IEC 60364-7-722 without charging controller re-designing


Compact design with 36mm width and 80mm length that saves 50% more space in installation

Flexible wiring

Possible in feeding from both bottom and up terminals no matter if it is installed in EV chargers or in distribution boards/consumer units


Significant cost-saving compared to type-B RCD while maintaining a high level of protection described by the IEC/EN standard for EV charging


Joint design by a group of reputable RCD experts and assembled at carefully selected partners with track records

Global availability

Accepted in most European and Asian countries with its compliance with IEC/EN 61009-1 and IEC 62955 standard


The eFAB Type-EV RCBO is an integrated type-A residual current circuit breaker with over-current protection (type-A RCBO) and residual direct current protective devices (RDC-PD). It is designed for the EV charging system to meet residual current protection requested by IEC 61851-1 & IEC 60364-7-722. Both AC 30mA (A Type) and 6 mA DC residual current protection are integrated into the device with a compact design.

The device is globally the first type-EV RCBO (Type-A RCBO and RDC-PD complying with IEC 62955 ) certified by TÜV Rheinland. It suits perfectly for the IEC market where voltage-dependent Type-A RCBO is accepted – such as China, ASEAN and UK.
