NEW: Type- EV RCBO At 36mm Width For 3.5/7kW Mode-3 EV Charging

At the beginning of 2021, Bituo introduced a new RCBO used for residual current protection at mode-3 Electrical Vehicle (EV) charging. Our new 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 device (RDC-PD).  The product is designed for a mode-3 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 is integrated into the device with 36mm width.

Unlike RDC-MD and mRCD complying with IEC 629555 and IEC 60947-2-(M) respectively, the eFAB type-EV RCBO trips independent of main-circuit relays/contactors in the occurrence of AC/DC fault current (see configuration 3). It is an ideal solution for EV charger manufacturers and installers that mitigate their risks of being involved in electrical accidents.

Customer Benefits

• Easy-to-use: Installation alone can help EV charger meet residual current protection requested by IEC 61851-1 & IEC 60364-7-722 without charging controller re-designing

•  Space-saving: Compact design with 36mm (2MW) width and 80mm length that saves 50% more space in installation than the traditional 4MW combination of 2MW MCB and 2.5MW type-EV/B RCCB

• 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

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

• High-quality: Designed by reputable RCD experts and assembled at carefully selected partners with track records of assembling RCD at a high standard

• Smart operation: Automatic re-closing devices/motor operation accessories available to facility remote/local testing and resetting without opening of EV charger cabinet

• Global availability: Accepted in most of the European and Asian countries with its compliance with IEC/EN 61009-1 and IEC 62955 standard
